Solution Architecture Definition 1:
Solution architecture is a practice of defining and describing an architecture of a system delivered in context of a specific solution and as such it may encompass description of an entire system or only its specific parts. Definition of a solution architecture is typically led by a solution architect.
Solution Architecture Definition 2:
The AWS Certified Solutions Architect – Associate examination is intended for individuals who perform a solutions architect role and have one or more years of hands-on experience designing available, cost-efficient, fault-tolerant, and scalable distributed systems on AWS.
- Take an AWS Training Class
- Study AWS Whitepapers and FAQs: AWS Well-Architected webpage (various whitepapers linked)
- If you are running an application in a production environment and must add a new EBS volume with data from a snapshot, what could you do to avoid degraded performance during the volume’s first use?
Initialize the data by reading each storage block on the volume.
Volumes created from an EBS snapshot must be initialized. Initializing occurs the first time a storage block on the volume is read, and the performance impact can be impacted by up to 50%. You can avoid this impact in production environments by pre-warming the volume by reading all of the blocks.
- If you are running a legacy application that has hard-coded static IP addresses and it is running on an EC2 instance; what is the best failover solution that allows you to keep the same IP address on a new instance?
Elastic IP addresses (EIPs) are designed to be attached/detached and moved from one EC2 instance to another. They are a great solution for keeping a static IP address and moving it to a new instance if the current instance fails. This will reduce or eliminate any downtime uses may experience.
- Which feature of Intel processors help to encrypt data without significant impact on performance?
- You can mount to EFS from which two of the following?
- On-prem servers running Linux
- EC2 instances running Linux
EFS is not compatible with Windows operating systems.
When a file(s) is encrypted and the stored data is not in transit it’s known as encryption at rest. What is an example of encryption at rest?
When would vertical scaling be necessary? When an application is built entirely into one source code, otherwise known as a monolithic application.
Fault-Tolerance allows for continuous operation throughout a failure, which can lead to a low Recovery Time Objective. RPO vs RTO
- High-Availability means automating tasks so that an instance will quickly recover, which can lead to a low Recovery Time Objective. RPO vs. RTO
- Frequent backups reduce the time between the last backup and recovery point, otherwise known as the Recovery Point Objective. RPO vs. RTO
- Which represents the difference between Fault-Tolerance and High-Availability? High-Availability means the system will quickly recover from a failure event, and Fault-Tolerance means the system will maintain operations during a failure.
- From a security perspective, what is a principal? An anonymous user falls under the definition of a principal. A principal can be an anonymous user acting on a system.
An authenticated user falls under the definition of a principal. A principal can be an authenticated user acting on a system.
- What are two types of session data saving for an Application Session State? Stateless and Stateful
23. It is the customer’s responsibility to patch the operating system on an EC2 instance.
24. In designing an environment, what four main points should a Solutions Architect keep in mind? Cost-efficient, secure, application session state, undifferentiated heavy lifting: These four main points should be the framework when designing an environment.
25. In the context of disaster recovery, what does RPO stand for? RPO is the abbreviation for Recovery Point Objective.
26. What are the benefits of horizontal scaling?
Vertical scaling can be costly while horizontal scaling is cheaper.
Horizontal scaling suffers from none of the size limitations of vertical scaling.
Having horizontal scaling means you can easily route traffic to another instance of a server.

What means undifferentiated heavy lifting?
The reality, of course, today is that if you come up with a great idea you don’t get to go quickly to a successful product. There’s a lot of undifferentiated heavy lifting that stands between your idea and that success. The kinds of things that I’m talking about when I say undifferentiated heavy lifting are things like these: figuring out which servers to buy, how many of them to buy, what time line to buy them.
Eventually you end up with heterogeneous hardware and you have to match that. You have to think about backup scenarios if you lose your data center or lose connectivity to a data center. Eventually you have to move facilities. There’s negotiations to be done. It’s a very complex set of activities that really is a big driver of ultimate success.
But they are undifferentiated from, it’s not the heart of, your idea. We call this muck. And it gets worse because what really happens is you don’t have to do this one time. You have to drive this loop. After you get your first version of your idea out into the marketplace, you’ve done all that undifferentiated heavy lifting, you find out that you have to cycle back. Change your idea. The winners are the ones that can cycle this loop the fastest.
On every cycle of this loop you have this undifferentiated heavy lifting, or muck, that you have to contend with. I believe that for most companies, and it’s certainly true at Amazon, that 70% of your time, energy, and dollars go into the undifferentiated heavy lifting and only 30% of your energy, time, and dollars gets to go into the core kernel of your idea.
I think what people are excited about is that they’re going to get a chance they see a future where they may be able to invert those two. Where they may be able to spend 70% of their time, energy and dollars on the differentiated part of what they’re doing.

Testimonial: Passed SAA-C02!
So my exam was yesterday and I got the results in 24 hours. I think that’s how they review all saa exams, not showing the results right away anymore.
I scored 858. Was practicing with Stephan’s udemy lectures and Bonso exam tests. My test results were as follows Test 1. 63%, 93% Test 2. 67%, 87% Test 3. 81 % Test 4. 72% Test 5. 75 % Test 6. 81% Stephan’s test. 80%
I was reading all question explanations (even the ones I got correct)
The actual exam was pretty much similar to these. The topics I got were:
A lot of S3 (make sure you know all of it from head to toes)
DataSync and Database Migration Service in same questions. Make sure you know the difference
One EKS question
2-3 KMS questions
Security group question
A lot of RDS Multi-AZ
SQS + SNS fan out pattern
ECS microservice architecture question
And that’s all I can remember)
I took extra 30 minutes, because English is not my native language and I had plenty of time to think and then review flagged questions.
Good luck with your exams guys!
Testimonial: Passed SAA-C02
Hey guys, just giving my update so all of you guys working towards your certs can stay motivated as these success stories drove me to reach this goal.
Background: 12 years of military IT experience, never worked with the cloud. I’ve done 7 deployments (that is a lot in 12 years), at which point I came home from the last one burnt out with a family that barely knew me. I knew I needed a change, but had no clue where to start or what I wanted to do. I wasn’t really interested in IT but I knew it’d pay the bills. After seeing videos about people in IT working from home(which after 8+ years of being gone from home really appealed to me), I stumbled across a video about a Solutions Architect’s daily routine working from home and got me interested in AWS.
It took me 68 days straight of hard work to pass this exam with confidence. No rest days, more than 120 pages of hand-written notes and hundreds and hundreds of flash cards.
In the beginning, I hopped on Stephane Maarek’s course for the CCP exam just to see if it was for me. I did the course in about a week and then after doing some research on here, got the CCP Practice exams from tutorialsdojo.com Two weeks after starting the Udemy course, I passed the exam. By that point, I’d already done lots of research on the different career paths and the best way to study, etc.
Cantrill(10/10) – That same day, I hopped onto Cantrill’s course for the SAA and got to work. Somebody had mentioned that by doing his courses you’d be over-prepared for the exam. While I think a combination of material is really important for passing the certification with confidence, I can say without a doubt Cantrill’s courses got me 85-90% of the way there. His forum is also amazing, and has directly contributed to me talking with somebody who works at AWS to land me a job, which makes the money I spent on all of his courses A STEAL. As I continue my journey (up next is SA Pro), I will be using all of his courses.
Neal Davis(8/10) – After completing Cantrill’s course, I found myself needing a resource to reinforce all the material I’d just learned. AWS is an expansive platform and the many intricacies of the different services can be tricky. For this portion, I relied on Neal Davis’s Training Notes series. These training notes are a very condensed version of the information you’ll need to pass the exam, and with the proper context are very useful to find the things you may have missed in your initial learnings. I will be using his other Training Notes for my other exams as well.
TutorialsDojo(10/10) – These tests filled in the gaps and allowed me to spot my weaknesses and shore them up. I actually think my real exam was harder than these, but because I’d spent so much time on the material I got wrong, I was able to pass the exam with a safe score.
As I said, I was surprised at how difficult the exam was. A lot of my questions were related to DBs, and a lot of them gave no context as to whether the data being loaded into them was SQL or NoSQL which made the choice selection a little frustrating. A lot of the questions have 2 VERY SIMILAR answers, and often time the wording of the answers could be easy to misinterpret (such as when you are creating a Read Replica, do you attach it to the primary application DB that is slowing down because of read issues or attach it to the service that is causing the primary DB to slow down). For context, I was scoring 95-100% on the TD exams prior to taking the test and managed a 823 on the exam so I don’t know if I got unlucky with a hard test or if I’m not as prepared as I thought I was (i.e. over-thinking questions).
Anyways, up next is going back over the practical parts of the course as I gear up for the SA Pro exam. I will be taking my time with this one, and re-learning the Linux CLI in preparation for finding a new job.
PS if anybody on here is hiring, I’m looking! I’m the hardest worker I know and my goal is to make your company as streamlined and profitable as possible. 🙂
Testimonial: How did you prepare for AWS Certified Solutions Architect – Associate Level certification?
Practical knowledge is 30% important and rest is Jayendra blog and Dumps.
Buying udemy courses doesn’t make you pass, I can tell surely without going to dumps and without going to jayendra’s blog not easy to clear the certification.
Read FAQs of S3, IAM, EC2, VPC, SQS, Autoscaling, Elastic Load Balancer, EBS, RDS, Lambda, API Gateway, ECS.
Read the Security Whitepaper and Shared Responsibility model.
The most important thing is basic questions from the last introduced topics to the exam is very important like Amazon Kinesis, etc…
– ACloudGuru course with practice test’s
– Created my own cheat sheet in excel
– Practice questions on various website
– Few AWS services FAQ’s
– Some questions were your understanding about which service to pick for the use case.
– many questions on VPC
– a couple of unexpected question on AWS CloudHSM, AWS systems manager, aws athena
– encryption at rest and in transit services
– migration from on-premise to AWS
– backup data in az vs regional
I believe the time was sufficient.
Overall I feel AWS SAA was more challenging in theory than GCP Associate CE.
some resources I bookmarked:
- Comparison of AWS Services
- Solutions Architect – Associate | Qwiklabs
- A curated list of AWS resources to prepare for the AWS Certifications
- AWS Cheat Sheet
Whitepapers are the important information about each services that are published by Amazon in their website. If you are preparing for the AWS certifications, it is very important to use the some of the most recommended whitepapers to read before writing the exam.
- Overview of Security Processes
- Storage Options in the Cloud
- Defining Fault Tolerant Applications in the AWS Cloud
- Overview of Amazon Web Services
- Compliance Whitepaper
- Architecting for the AWS Cloud
Data Security questions could be the more challenging and it’s worth noting that you need to have a good understanding of security processes described in the whitepaper titled “Overview of Security Processes”.
In the above list, most important whitepapers are Overview of Security Processes and Storage Options in the Cloud. Read more here…

Testimonial: I passed SAA-C02… But don’t do what I did to pass it
I’ve been following this subreddit for awhile and gotten some helpful tips, so I’d like to give back with my two cents. FYI I passed the exam 788
The exam materials that I used were the following:
AWS Certified Solutions Architect Associate All-in-One Exam Guide (Banerjee)
Stephen Maarek’s Udemy course, and his 6 exam practices
Adrian Cantrill’s online course (about `60% done)
(My company has udemy business account so I was able to use Stephen’s course/exam)
I scheduled my exam at the end of March, and started with Adrian’s. But I was dumb thinking that I could go through his course within 3 weeks… I stopped around 12% of his course and went to the textbook and finished reading the all-in-one exam guide within a weekend. Then I started going through Stephen’s course. While learning the course, I pushed back the exam to end of April, because I knew I wouldn’t be ready by the exam comes along.
Five days before the exam, I finished Stephen’s course, and then did his final exam on the course. I failed miserably (around 50%). So I did one of Stephen’s practice exam and did worse (42%). I thought maybe it might be his exams that are slightly difficult, so I went and bought Jon Bonso’s exam and got 60% on his first one. And then I realized based on all the questions on the exams, I was definitely lacking some fundamentals. I went back to Adrian’s course and things were definitely sticking more – I think it has to do with his explanations + more practical stuff. Unfortunately, I could not finish his course before the exam (because I was cramming), and on the day of the exam, I could only do Bonso’s four of six exams, with barely passing one of them.
Please, don’t do what I did. I was desperate to get this thing over with it. I wanted to move on and work on other things for job search, but if you’re not in this situation, please don’t do this. I can’t for love of god tell you about OAI and Cloudfront and why that’s different than S3 URL. The only thing that I can remember is all the practical stuff that I did with Adrian’s course. I’ll never forget how to create VPC, because he make you manually go through it. I’m not against Stephen’s course – they are different on its own way (see the tips below).
So here’s what I recommend doing before writing for aws exam:
Don’t schedule your exam beforehand. Go through the materials that you are doing, and make sure you get at least 80% on all of the Jon Bonso’s exam (I’d recommend maybe 90% or higher)
If you like to learn things practically, I do recommend Adrian’s course. If you like to learn things conceptually, go with Stephen Maarek’s course. I find Stephen’s course more detailed when going through different architectures, but I can’t really say that because I didn’t really finish Adrian’s course
Jon Bonso’s exam was about the same difficulty as the actual exam. But they’re slightly more tricky. For example, many of the questions will give you two different situation and you really have to figure out what they are asking for because they might contradict to each other, but the actual question is asking one specific thing. However, there were few questions that were definitely obvious if you knew the service.
I’m upset that even though I passed the exam, I’m still lacking some practical stuff, so I’m just going to go through Adrian’s Developer exam but without cramming this time. If you actually learn the materials and practice them, they are definitely useful in the real world. I hope this will help you passing and actually learning the stuff.
P.S I vehemently disagree with Adrian in one thing in his course. doggogram.io is definitely better than catagram.io, although his cats are pretty cool
Testimonial: I passed the SAA-C02 exam!
I sat the exam at a PearsonVUE test centre and scored 816.
The exam had lots of questions around S3, RDS and storage. To be honest it was a bit of a blur but they are the ones I remember.
I was a bit worried before sitting the exam as I was only hit 76% in the official AWS practice exam the night before but it turned out alright in the end!
I have around 8 years of experience in IT but AWS was relatively new to me around 5 weeks ago.
Training Material Used
Firstly I ran through the u/stephanemaarek course which I found to pretty much cover all that was required!
I then used the u/Tutorials_Dojo practice exams. I took one before starting Stephane’s course to see where I was at with no training. I got 46% but I suppose a few of them were lucky guesses!
I then finished the course and took another test and hit around 65%, TD was great as they gave explanations on the answers. I then used this go back to the course to go over my weak areas again.
I then seemed to not be able to get higher than the low 70% on the exams so I went through u/neal-davis course, this was also great as it had an “Exam Cram” video at the end of each topic.
I also set up flashcards on BrainScape which helped me remember AWS services and what their function is.
All in all it was a great learning experience and I look forward to putting my skills into action!
Many FSx / EFS / Lustre questions
S3 Use cases, storage tiers, cloudfront were pretty prominent too
Only got one “figure out what’s wrong with this IAM policy” question
A handful of dynamodb questions and a handful for picking use cases between different database types or caching layers.
Other typical tips: When you’re unclear on what answer you should pick, or if they seem very similar – work on eliminating answers first. “It can’t be X because oy Y” and that can help a lot.
Testimonial: Passed the AWS Solutions Architect Associate exam!
I prepared mostly from freely available resources as my basics were strong. Bought Jon Bonso’s tests on Udemy and they turned out to be super important while preparing for those particular type of questions (i.e. the questions which feel subjective, but they aren’t), understanding line of questioning and most suitable answers for some common scenarios.
Created a Notion notebook to note down those common scenarios, exceptions, what supports what, integrations etc. Used that notebook and cheat sheets on Tutorials Dojo website for revision on final day.
Found the exam was little tougher than Jon Bonso’s, but his practice tests on Udemy were crucial. Wouldn’t have passed it without them.
Piece of advice for upcoming test aspirants: Get your basics right, especially networking. Understand properly how different services interact in VPC. Focus more on the last line of the question. It usually gives you a hint upon what exactly is needed. Whether you need cost optimization, performance efficiency or high availability. Little to no operational effort means serverless. Understand all serverless services thoroughly.
Testimonial: Passed Solutions Architect Associate (SAA-C02) Today!
I have almost no experience with AWS, except for completing the Certified Cloud Practitioner earlier this year. My work is pushing all IT employees to complete some cloud training and certifications, which is why I chose to do this.
How I Studied:
My company pays for acloudguru subscriptions for its employees, so I used that for the bulk of my learning. I took notes on 3×5 notecards on the key terms and concepts for review.
Once I scored passing grades on the ACG practice tests, I took the Jon Bonso tests on Udemy, which are much more difficult and fairly close to the difficulty of the actual exam. I scored 45%-74% on every Bonso practice test, and spent 1-2 hours after each test reviewing what I missed, supplementing my note cards, and taking time to understand my weak spots. I only took these tests once each, but in between each practice test, I would review all my note cards until I had the content largely memorized.
This was one of the most difficult certification tests I’ve ever done. The exam was remote proctored with PearsonVUE (I used PSI for the CCP and didn’t like it as much) I felt like I was failing half the time. I marked about 25% of the questions for review, and I used up the entire allotted time. The questions are mostly about understanding which services interact with which other services, or which services are incompatible with the scenario. It was important for me to read through each response and eliminate the ones that don’t make sense. A lot of the responses mentioned a lot of AWS services that sound good but don’t actually work together (i.e. if it doesn’t make sense to have service X querying database Y, so that probably isn’t the right answer). I can’t point to one domain that really needs to be studied more than any other. You need to know all of the content for the exam.
The ACG practice tests are not a good metric for success for the actual SAA exam, and I would not have passed without Bonso’s tests showing me my weak spots. PearsonVUE is better than PSI. Make sure to study everything thoroughly and review excessively. You don’t necessarily need 5 different study sources and years of experience to be able to pass (although both of those definitely help) and good luck to anyone that took the time to read!
Testimonial: Passed AWS CSAA today!
AWS Certified Solutions Architect Associate
So glad to pass my first AWS certification after 6 weeks of preparation.
After a series of trial of error in regards to picking the appropriate learning content. Eventually, I went with the community’s advice, and took the course presented by the amazing u/stephanemaarek, in addition to the practice exams by Jon Bonso.
At this point, I can’t say anything that hasn’t been said already about how helpful they are. It’s a great combination of learning material, I appreciate the instructor’s work, and the community’s help in this sub.
Throughout the course I noted down the important points, and used the course slides as a reference in the first review iteration.
Before resorting to Udemy’s practice exams, I purchased a practice exam from another website, that I regret (not to defame the other vendor, I would simply recommend Udemy).
Udemy’s practice exams were incredible, in that they made me aware of the points I hadn’t understood clearly. After each exam, I would go both through the incorrect answers, as well as the questions I marked for review, wrote down the topic for review, and read the explanation thoroughly. The explanations point to the respective documentation in AWS, which is a recommended read, especially if you don’t feel confident with the service.
What I want to note, is that I didn’t get satisfying marks on the first go at the practice exams (I got an average of ~70%).
Throughout the 6 practice exams, I aggregated a long list of topics to review, went back to the course slides and practice-exams explanations, in addition to the AWS documentation for the respective service.
On the second go I averaged 85%. The second attempt at the exams was important as a confidence boost, as I made sure I understood the services more clearly.
The take away:
Don’t feel disappointed if you get bad results at your practice-exams. Make sure to review the topics and give it another shot.
The AWS documentation is your friend! It is vert clear and concise. My only regret is not having referenced the documentation enough after learning new services.
I scheduled the exam using PSI.
I was very confident going into the exam. But going through such an exam environment for the first time made me feel under pressure. Partly, because I didn’t feel comfortable being monitored (I was afraid to get eliminated if I moved or covered my mouth), but mostly because there was a lot at stake from my side, and I had to pass it in the first go.
The questions were harder than expected, but I tried analyze the questions more, and eliminate the invalid answers.
I was very nervous and kept reviewing flagged questions up to the last minute. Luckily, I pulled through.
The take away:
The proctors are friendly, just make sure you feel comfortable in the exam place, and use the practice exams to prepare for the actual’s exam’s environment. That includes sitting in a straight posture, not talking/whispering, or looking away.
Make sure to organize the time dedicated for each questions well, and don’t let yourself get distracted by being monitored like I did.
Don’t skip the question that you are not sure of. Try to select the most probable answer, then flag the question. This will make the very-stressful, last-minute review easier.
You have been engaged by a company to design and lead a migration to an AWS environment. The team is concerned about the capabilities of the new environment, especially when it comes to high availability and cost-effectiveness. The design calls for about 20 instances (c3.2xlarge) pulling jobs/messages from SQS. Network traffic per instance is estimated to be around 500 Mbps at the beginning and end of each job. Which configuration should you plan on deploying?
Spread the Instances over multiple AZs to minimize the traffic concentration and maximize fault-tolerance. With a multi-AZ configuration, an additional reliability point is scored as the entire Availability Zone itself is ruled out as a single point of failure. This ensures high availability. Wherever possible, use simple solutions such as spreading the load out rather than expensive high tech solutions
To save money, you quickly stored some data in one of the attached volumes of an EC2 instance and stopped it for the weekend. When you returned on Monday and restarted your instance, you discovered that your data was gone. Why might that be?
The volume was ephemeral, block-level storage. Data on an instance store volume is lost if an instance is stopped.
The most likely answer is that the EC2 instance had an instance store volume attached to it. Instance store volumes are ephemeral, meaning that data in attached instance store volumes is lost if the instance stops.
Reference: Instance store lifetime
Your company likes the idea of storing files on AWS. However, low-latency service of the last few days of files is important to customer service. Which Storage Gateway configuration would you use to achieve both of these ends?
A file gateway simplifies file storage in Amazon S3, integrates to existing applications through industry-standard file system protocols, and provides a cost-effective alternative to on-premises storage. It also provides low-latency access to data through transparent local caching.
Cached volumes allow you to store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally. Cached volumes offer a substantial cost savings on primary storage and minimize the need to scale your storage on-premises. You also retain low-latency access to your frequently accessed data.
You’ve been commissioned to develop a high-availability application with a stateless web tier. Identify the most cost-effective means of reaching this end.
Use an Elastic Load Balancer, a multi-AZ deployment of an Auto-Scaling group of EC2 Spot instances (primary) running in tandem with an Auto-Scaling group of EC2 On-Demand instances (secondary), and DynamoDB.
With proper scripting and scaling policies, running EC2 On-Demand instances behind the Spot instances will deliver the most cost-effective solution because On-Demand instances will only spin up if the Spot instances are not available. DynamoDB lends itself to supporting stateless web/app installations better than RDS .
You are building a NAT Instance in an m3.medium using the AWS Linux2 distro with amazon-linux-extras installed. Which of the following do you need to set?
Ensure that “Source/Destination Checks” is disabled on the NAT instance. With a NAT instance, the most common oversight is forgetting to disable Source/Destination Checks. TNote: This is a legacy topic and while it may appear on the AWS exam it will only do so infrequently.
You are reviewing Change Control requests and you note that there is a proposed change designed to reduce errors due to SQS Eventual Consistency by updating the “DelaySeconds” attribute. What does this mean?
When a new message is added to the SQS queue, it will be hidden from consumer instances for a fixed period.
Delay queues let you postpone the delivery of new messages to a queue for a number of seconds, for example, when your consumer application needs additional time to process messages. If you create a delay queue, any messages that you send to the queue remain invisible to consumers for the duration of the delay period. The default (minimum) delay for a queue is 0 seconds. The maximum is 15 minutes. To set delay seconds on individual messages, rather than on an entire queue, use message timers to allow Amazon SQS to use the message timer’s DelaySeconds value instead of the delay queue’s DelaySeconds value. Reference: Amazon SQS delay queues.
Amazon SQS keeps track of all tasks and events in an application: True or False?
False. Amazon SWF (not Amazon SQS) keeps track of all tasks and events in an application. Amazon SQS requires you to implement your own application-level tracking, especially if your application uses multiple queues. Amazon SWF FAQs.
You work for a company, and you need to protect your data stored on S3 from accidental deletion. Which actions might you take to achieve this?
Allow versioning on the bucket and to protect the objects by configuring MFA-protected API access.
Your Security Manager has hired a security contractor to audit your network and firewall configurations. The consultant doesn’t have access to an AWS account. You need to provide the required access for the auditing tasks, and answer a question about login details for the official AWS firewall appliance. Which actions might you do?
AWS has removed the Firewall appliance from the hub of the network and implemented the firewall functionality as stateful Security Groups, and stateless subnet NACLs. This is not a new concept in networking, but rarely implemented at this scale.
Create an IAM user for the auditor and explain that the firewall functionality is implemented as stateful Security Groups, and stateless subnet NACLs
Amazon ElastiCache can fulfill a number of roles. Which operations can be implemented using ElastiCache for Redis.
Amazon ElastiCache offers a fully managed Memcached and Redis service. Although the name only suggests caching functionality, the Redis service in particular can offer a number of operations such as Pub/Sub, Sorted Sets and an In-Memory Data Store. However, Amazon ElastiCache for Redis doesn’t support multithreaded architectures.
You have been asked to deploy an application on a small number of EC2 instances. The application must be placed across multiple Availability Zones and should also minimize the chance of underlying hardware failure. Which actions would provide this solution?
Deploy the EC2 servers in a Spread Placement Group.
Spread Placement Groups are recommended for applications that have a small number of critical instances which need to be kept separate from each other. Launching instances in a Spread Placement Group reduces the risk of simultaneous failures that might occur when instances share the same underlying hardware. Spread Placement Groups provide access to distinct hardware, and are therefore suitable for mixing instance types or launching instances over time. In this case, deploying the EC2 instances in a Spread Placement Group is the only correct option.
You manage a NodeJS messaging application that lives on a cluster of EC2 instances. Your website occasionally experiences brief, strong, and entirely unpredictable spikes in traffic that overwhelm your EC2 instances’ resources and freeze the application. As a result, you’re losing recently submitted messages from end-users. You use Auto Scaling to deploy additional resources to handle the load during spikes, but the new instances don’t spin-up fast enough to prevent the existing application servers from freezing. Can you provide the most cost-effective solution in preventing the loss of recently submitted messages?
Use Amazon SQS to decouple the application components and keep the messages in queue until the extra Auto-Scaling instances are available.
Neither increasing the size of your EC2 instances nor maintaining additional EC2 instances is cost-effective, and pre-warming an ELB signifies that these spikes in traffic are predictable. The cost-effective solution to the unpredictable spike in traffic is to use SQS to decouple the application components.
True statements on S3 URL styles
Virtual-host-style URLs (such as: https://bucket-name.s3.Region.amazonaws.com/key name) are supported by AWS.
Path-Style URLs (such as https://s3.Region.amazonaws.com/bucket-name/key name) are supported by AWS.
You run an automobile reselling company that has a popular online store on AWS. The application sits behind an Auto Scaling group and requires new instances of the Auto Scaling group to identify their public and private IP addresses. How can you achieve this?
Using a Curl or Get Command to get the latest meta-data from http://169.254.169.254/latest/meta-data/
What data formats are used to create CloudFormation templates?
JSOn and YAML
You have launched a NAT instance into a public subnet, and you have configured all relevant security groups, network ACLs, and routing policies to allow this NAT to function. However, EC2 instances in the private subnet still cannot communicate out to the internet. What troubleshooting steps should you take to resolve this issue?
Disable the Source/Destination Check on your NAT instance.
A NAT instance sends and retrieves traffic on behalf of instances in a private subnet. As a result, source/destination checks on the NAT instance must be disabled to allow the sending and receiving traffic for the private instances. Route 53 resolves DNS names, so it would not help here. Traffic that is originating from your NAT instance will not pass through an ELB. Instead, it is sent directly from the public IP address of the NAT Instance out to the Internet.
You need a storage service that delivers the lowest-latency access to data for a database running on a single EC2 instance. Which of the following AWS storage services is suitable for this use case?
Amazon EBS is a block level storage service for use with Amazon EC2. Amazon EBS can deliver performance for workloads that require the lowest-latency access to data from a single EC2 instance. A broad range of workloads, such as relational and non-relational databases, enterprise applications, containerized applications, big data analytics engines, file systems, and media workflows are widely deployed on Amazon EBS.
What are DynamoDB use cases?
Use cases include storing JSON data, BLOB data and storing web session data.
You are reviewing Change Control requests, and you note that there is a change designed to reduce costs by updating the Amazon SQS “WaitTimeSeconds” attribute. What does this mean?
When the consumer instance polls for new work, the SQS service will allow it to wait a certain time for one or more messages to be available before closing the connection.
Poor timing of SQS processes can significantly impact the cost effectiveness of the solution.
Long polling helps reduce the cost of using Amazon SQS by eliminating the number of empty responses (when there are no messages available for a ReceiveMessage request) and false empty responses (when messages are available but aren’t included in a response).
You have been asked to decouple an application by utilizing SQS. The application dictates that messages on the queue CAN be delivered more than once, but must be delivered in the order they have arrived while reducing the number of empty responses. Which option is most suitable?
Configure a FIFO SQS queue and enable long polling.
You are a security architect working for a large antivirus company. The production environment has recently been moved to AWS and is in a public subnet. You are able to view the production environment over HTTP. However, when your customers try to update their virus definition files over a custom port, that port is blocked. You log in to the console and you allow traffic in over the custom port. How long will this take to take effect?
You need to restrict access to an S3 bucket. Which methods can you use to do so?
There are two ways of securing S3, using either Access Control Lists (Permissions) or by using bucket Policies.
You are reviewing Change Control requests, and you note that there is a change designed to reduce wasted CPU cycles by increasing the value of your Amazon SQS “VisibilityTimeout” attribute. What does this mean?
When a consumer instance retrieves a message, that message will be hidden from other consumer instances for a fixed period.
Poor timing of SQS processes can significantly impact the cost effectiveness of the solution. To prevent other consumers from processing the message again, Amazon SQS sets a visibility timeout, a period of time during which Amazon SQS prevents other consumers from receiving and processing the message. The default visibility timeout for a message is 30 seconds. The minimum is 0 seconds. The maximum is 12 hours.
With EBS, I can ____.
Create an encrypted volume from a snapshot of another encrypted volume.
Create an encrypted snapshot from an unencrypted snapshot by creating an encrypted copy of the unencrypted snapshot.
You can create an encrypted volume from a snapshot of another encrypted volume.
Although there is no direct way to encrypt an existing unencrypted volume or snapshot, you can encrypt them by creating either a volume or a snapshot. Reference: Encrypting unencrypted resources.
Following advice from your consultant, you have configured your VPC to use dedicated hosting tenancy. Your VPC has an Amazon EC2 Auto Scaling designed to launch or terminate Amazon EC2 instances on a regular basis, in order to meet workload demands. A subsequent change to your application has rendered the performance gains from dedicated tenancy superfluous, and you would now like to recoup some of these greater costs. How do you revert your instance tenancy attribute of a VPC to default for new launched EC2 instances?
Modify the instance tenancy attribute of your VPC from dedicated to default using the AWS CLI, an AWS SDK, or the Amazon EC2 API.
You can change the instance tenancy attribute of a VPC from dedicated to default. Modifying the instance tenancy of the VPC does not affect the tenancy of any existing instances in the VPC. The next time you launch an instance in the VPC, it has a tenancy of default, unless you specify otherwise during launch. You can modify the instance tenancy attribute of a VPC using the AWS CLI, an AWS SDK, or the Amazon EC2 API only. Reference: Change the tenancy of a VPC.
What is Amazon DynamoDB?
Amazon DynamoDB is a fast, fully managed NoSQL database service. DynamoDB makes it simple and cost-effective to store and retrieve any amount of data and serve any level of request traffic.
DynamoDB is used to create tables that store and retrieve any level of data.
- DynamoDB uses SSD’s to store data.
- Provides Automatic and synchronous data.
- Maximum item size is 400KB
- Supports cross-region replication.
DynamoDB Core Concepts:
- The fundamental concepts around DynamoDB are:
- Tables-which is a collection of data.
- Items- They are the individual entries in the table.
- Attributes- These are the properties associated with the entries.
- Primary Keys.
- Secondary Indexes.
- DynamoDB streams.
- The Secondary index is a data structure that contains a subset of attributes from the table, along with an alternate key that supports Query operations.
- Every secondary index is related to only one table, from where it obtains data. This is called base table of the index.
- When you create an index you create an alternate key for the index i.e. Partition Key and Sort key, DynamoDB creates a copy of the attributes into the index, including primary key attributes derived from the table.
- After this is done, you use the query/scan in the same way as you would use a query on a table.
Every secondary index is instinctively maintained by DynamoDB.
DynamoDB Indexes: DynamoDB supports two indexes:
- Local Secondary Index (LSI)- The index has the same partition key as the base table but a different sort key,
- Global Secondary index (GSI)- The index has a partition key and sort key are different from those on the base table.
While creating more than one table using secondary table , you must do it in a sequence. Create table one after the another. When you create the first table wait for it to be active.
Once that table is active, create another table and wait for it to get active and so on. If you try to create one or more tables continuously DynamoDB will return a LimitExceededException.
You must specify the following, for every secondary index:
- Type- You must mention the type of index you are creating whether it is a Global Secondary Index or a Local Secondary index.
- Name- You must specify the name for the index. The rules for naming the indexes are the same as that for the table it is connected with. You can use the same name for the indexes that are connected with the different base table.
- Key- The key schema for the index states that every attribute in the index must be of the top level attribute of type-string, number, or binary. Other data types which include documents and sets are not allowed. Other requirements depend on the type of index you choose.
- For GSI- The partitions key can be any scalar attribute of the base table.
Sort key is optional and this too can be any scalar attribute of the base table.
- For LSI- The partition key must be the same as the base table’s partition key.
The sort key must be a non-key table attribute.
- Additional Attributes: The additional attributes are in addition to the tables key attributes. They are automatically projected into every index. You can use attributes for any data type, including scalars, documents and sets.
- Throughput: The throughput settings for the index if necessary are:
- GSI: Specify read and write capacity unit settings. These provisioned throughput settings are not dependent on the base tables settings.
- LSI- You do not need to specify read and write capacity unit settings. Any read and write operations on the local secondary index are drawn from the provisioned throughput settings of the base table.
You can create upto 5 Global and 5 Local Secondary Indexes per table. With the deletion of a table all the indexes are connected with the table are also deleted.
You can use the Scan or Query operation to fetch the data from the table. DynamoDB will give you the results in descending or ascending order.
An NLB is a Network Load Balancer.
Network Load Balancer Overview: A Network Load Balancer functions at the fourth layer of the Open Systems Interconnection (OSI) model. It can handle millions of requests per second. After the load balancer receives a connection request, it selects a target from the target group for the default rule. It attempts to open a TCP connection to the selected target on the port specified in the listener configuration. When you enable an Availability Zone for the load balancer, Elastic Load Balancing creates a load balancer node in the Availability Zone. By default, each load balancer node distributes traffic across the registered targets in its Availability Zone only. If you enable cross-zone load balancing, each load balancer node distributes traffic across the registered targets in all enabled Availability Zones. It is designed to handle tens of millions of requests per second while maintaining high throughput at ultra low latency, with no effort on your part. The Network Load Balancer is API-compatible with the Application Load Balancer, including full programmatic control of Target Groups and Targets. Here are some of the most important features:
- Static IP Addresses – Each Network Load Balancer provides a single IP address for each Availability Zone in its purview. If you have targets in us-west-2a and other targets in us-west-2c, NLB will create and manage two IP addresses (one per AZ); connections to that IP address will spread traffic across the instances in all the VPC subnets in the AZ. You can also specify an existing Elastic IP for each AZ for even greater control. With full control over your IP addresses, a Network Load Balancer can be used in situations where IP addresses need to be hard-coded into DNS records, customer firewall rules, and so forth.
- Zonality – The IP-per-AZ feature reduces latency with improved performance, improves availability through isolation and fault tolerance, and makes the use of Network Load Balancers transparent to your client applications. Network Load Balancers also attempt to route a series of requests from a particular source to targets in a single AZ while still providing automatic failover should those targets become unavailable.
- Source Address Preservation – With Network Load Balancer, the original source IP address and source ports for the incoming connections remain unmodified, so application software need not support X-Forwarded-For, proxy protocol, or other workarounds. This also means that normal firewall rules, including VPC Security Groups, can be used on targets.
- Long-running Connections – NLB handles connections with built-in fault tolerance, and can handle connections that are open for months or years, making them a great fit for IoT, gaming, and messaging applications.
- Failover – Powered by Route 53 health checks, NLB supports failover between IP addresses within and across regions.
There are two types of VPC endpoints: (1) interface endpoints and (2) gateway endpoints. Interface endpoints enable connectivity to services over AWS PrivateLink.
Amazon AWS uses key pair to encrypt and decrypt login information.
A sender uses a public key to encrypt data, which its receiver then decrypts using another private key. These two keys, public and private, are known as a key pair.
You need a key pair to be able to connect to your instances. The way this works on Linux and Windows instances is different.
First, when you launch a new instance, you assign a key pair to it. Then, when you log in to it, you use the private key.
The difference between Linux and Windows instances is that Linux instances do not have a password already set and you must use the key pair to log in to Linux instances. On the other hand, on Windows instances, you need the key pair to decrypt the administrator password. Using the decrypted password, you can use RDP and then connect to your Windows instance.
Amazon EC2 stores only the public key, and you can either generate it inside Amazon EC2 or you can import it. Since the private key is not stored by Amazon, it’s advisable to store it in a secure place as anyone who has this private key can log in on your behalf.
There are two types of Security Groups based on where you launch your instance. When you launch your instance on EC2-Classic, you have to specify an EC2-Classic Security Group . On the other hand, when you launch an instance in a VPC, you will have to specify an EC2-VPC Security Group. Now that we have a clear understanding what we are comparing, lets see their main differences:
- When the instance is launched, you can only choose a Security Group that resides in the same region as the instance.
- You cannot change the Security Group after the instance has launched (you may edit the rules)
- They are not IPv6 Capable
- You can change the Security Group after the instance has launched
- They are IPv6 Capable
Generally speaking, they are not interchangeable and there are more capabilities on the EC2-VPC SGs. You may read more about them on Differences Between Security Groups for EC2-Classic and EC2-VPC
I think this is historical in nature. S3 and DynamoDB were the first services to support VPC endpoints. The release of those VPC endpoint features pre-dates two important services that subsequently enabled interface endpoints: Network Load Balancer and AWS PrivateLink.
- Separate the Lambda handler from your core logic.
- Take advantage of execution context reuse to improve the performance of your function. Initialize SDK clients and database connections outside of the function handler, and cache static assets locally in the
/tmpdirectory. Subsequent invocations processed by the same instance of your function can reuse these resources. This saves execution time and avoid potential data leaks across invocations, don’t use the execution context to store user data, events, or other information with security implications. If your function relies on a mutable state that can’t be stored in memory within the handler, consider creating a separate function or separate versions of a function for each user.
- Use AWS Lambda Environment Variables to pass operational parameters to your function. For example, if you are writing to an Amazon S3 bucket, instead of hard-coding the bucket name you are writing to, configure the bucket name as an environment variable.
You can use VPC Flow Logs. The steps would be the following:
- Enable VPC Flow Logs for the VPC your EC2 instance lives in. You can do this from the VPC console
- Having VPC Flow Logs enabled will create a CloudWatch Logs log group
- Find the Elastic Network Interface assigned to your EC2 instance. Also, get the private IP of your EC2 instance. You can do this from the EC2 console.
- Find the CloudWatch Logs log stream for that ENI.
- Search the log stream for records where your Windows instance’s IP is the destination IP, make sure the port is the one you’re looking for. You’ll see records that tell you if someone has been connecting to your EC2 instance. For example, there are bytes transferred, status=ACCEPT, log-status=OK. You will also know the source IP that connected to your instance.
I recommend using CloudWatch Logs Metric Filters, so you don’t have to do all this manually. Metric Filters will find the patterns I described in your CloudWatch Logs entries and will publish a CloudWatch metric. Then you can trigger an alarm that notifies you when someone logs in to your instance.
Here are more details from the AWS Official Blog and the AWS documentation for VPC Flow Logs records:
Also, there are 3rd-party tools that simplify all these steps for you and give you very nice visibility and alerts into what’s happening in your AWS network resources. I’ve tried Observable Networks and it’s great: Observable Networks
While enabling ports on AWS NAT gateway when you allow inbound traffic on port 80/443 , do you need to allow outbound traffic on the same ports or is it sufficient to allow outbound traffic on ephemeral ports (1024-65535)?
Typically outbound traffic is not blocked by NAT on any port, so you would not need to explicitly allow those, since they should already be allowed. Your firewall generally would have a rule to allow return traffic that was initiated outbound from inside your office.
Is AWS traffic between EC2 nodes in the same availability zone secure with respect to sending sensitive data?
According to Amazon’s documentation, it is impossible for one instance to sniff traffic bound for a different instance.
- Packet sniffing by other tenants. It is not possible for a virtual instance running in promiscuous mode to receive or “sniff” traffic that is intended for a different virtual instance. While you can place your interfaces into promiscuous mode, the hypervisor will not deliver any traffic to them that is not addressed to them. Even two virtual instances that are owned by the same customer located on the same physical host cannot listen to each other’s traffic. Attacks such as ARP cache poisoning do not work within Amazon EC2 and Amazon VPC. While Amazon EC2 does provide ample protection against one customer inadvertently or maliciously attempting to view another’s data, as a standard practice you should encrypt sensitive traffic.
But as you can see, they still recommend that you should maintain encryption inside your network. We have taken the approach of terminating SSL at the external interface of the ELB, but then initiating SSL from the ELB to our back-end servers, and even further, to our (RDS) databases. It’s probably belt-and-suspenders, but in my industry it’s needed. Heck, we have some interfaces that require HTTPS and a VPN.
What’s the use case for S3 Pre-signed URL for uploading objects?
I get the use-case to allow access to private/premium content in S3 using Presigned-url that can be used to view or download the file until the expiration time set, But what’s a real life scenario in which a Webapp would have the need to generate URI to give users temporary credentials to upload an object, can’t the same be done by using the SDK and exposing a REST API at the backend.
Asking this since I want to build a POC for this functionality in Java, but struggling to find a real-world use-case for the same
Pre-signed URLs are used to provide short-term access to a private object in your S3 bucket. They work by appending an AWS Access Key, expiration time, and Sigv4 signature as query parameters to the S3 object. There are two common use cases when you may want to use them:
- Simple, occasional sharing of private files.
- Frequent, programmatic access to view or upload a file in an application.
Imagine you may want to share a confidential presentation with a business partner, or you want to allow a friend to download a video file you’re storing in your S3 bucket. In both situations, you could generate a URL, and share it to allow the recipient short-term access.
There are a couple of different approaches for generating these URLs in an ad-hoc, one-off fashion, including:
- Using the AWS Tools for Powershell.
- Using the AWS CLI.

- How to check when a network request reached my Fargate server?by /u/Appropriate_Newt_238 (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 11:28 am
I have a server which recieves a webhook from one of our service providers and we have to respond within 2 seconds to it. Yesterday while debugging some failed scenarios (where my server wasn't able to respond within 2 seconds) I saw that the payload that was sent via the service provider reached my server after 10 whole seconds. According to my provider it's because of network latency, but come on, what kind of network latency can make a payload 10 seconds late. Right now I am logging the payload as soon as I get it to Cloudwatch, I wanna know if I can go a few layers deeper and check when the network payload was received to the actual IP? Honestly, I am not even sure where to look, can I check my LB logs or my VPC logs or my subnet logs to identify when the payload was received? Basically, I wanna know if there's network latency on their end or on mine. A few things about my setup, I have a VPC with 2 public subnets, my ECS fargate is in one of the public subnets, behind a ALB. Can someone nudge me in the right direction? submitted by /u/Appropriate_Newt_238 [link] [comments]
- What's the proper way to develop lambda functions and deploy to multiple environments?by /u/pypipper (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 10:50 am
Hello, let's assume the following: I have a production, test, and development environment. Ideally, development environment is local, not too passionate, it could also be another AWS account or can be merged with the testing environment. How could one develop these functions in a convenient way? So far, for toy projects, I would do local development, then upload manually to production in Lambda dashboard, test it in the Lambda dashboard, if problems, work again locally, re-upload, re-test etc. This is with ONE environment. Therefore, I was wondering if there is a better way to do this. For example: - I work locally on the lambda code during its development, yet somehow it communicates with AWS services (for example DynamoDB) in a development environment. - Once the lambda works in the local/development environment, I can look into "pushing" it to the test environment, once tested and happy, push it to "production". - But not having to zip the code, upload individually, more something like Git push. How do you do your lambda dev-test-release cycle? submitted by /u/pypipper [link] [comments]
- Best way to configure an ALB with Nginx on EKSby /u/Macscroge (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 10:38 am
I previously installed nginx on my EKS cluster using a helm chart(nginx-stable repo) However the Helm chart is only capable of creating ELB or NLB load balancers, not ALB. I have gotten an ALB working by hacking away at the service.yaml after the chart is applied but obviously this isn't a good way of doing things. What's the best way of doing this? Should I create the nginx manifests manually or is there a way of doing this through helm? submitted by /u/Macscroge [link] [comments]
- Microservice Development with Java : EC2/Elastic BeanStalk Vs Lambdaby /u/wishiwereignorant (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 9:41 am
I am working on a project that will be based on Micro-service Architecture. Different micro-services will be developed by different teams in Different Languages ( Ruby, Node.js, Java etc ) The plan is to use Lambda with API Gateway to create the Endpoints in addition to Aurora DB and S3 for data persistence. My question is, Is AWS Lambda a good option to deploy an entire webapp backend ? Coming from Spring Boot Backend, I cannot wrap my head around the idea of having lots of entity classes, service classes all wrapped in a Lambda Function ( as its meant to be small ). Not to mention the overhead of using Dependencies such as Hibernate etc, which further increases the size of the app and hence start up time of Lambdas. Will using EC2 or Elastic Beanstalk be better in this situation ? How about the difference in price in both cases. Thanks in advance. submitted by /u/wishiwereignorant [link] [comments]
- Is there a way to troubleshoot my DNS records on route 53?by /u/tomacdmota (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 7:39 am
Hey guys, So I transferred my domain from Namecheap to route 53 yesterday. I have a web app hosted with Amplify. I am trying to connect the domain to it but for some reason, I am getting stuck on the "SSL configuration" bit. Now, from my understanding, it automatically adds the CNAME record required for this verification to happen. I have checked on route 53 and the record has indeed been created and is there. However, when I use something like https://www.whatsmydns.net/#CNAME/www.trustmotores.com (that is the domain and record in question), it fails in every place in the world. I have read the documentation but couldn't find anything on this. The record is created but isn't working? My guess yesterday was that since I had just transferred the domain, I needed to wait for it to propagate, but has been over 14h and still nothing. Any guesses?Thank you. https://preview.redd.it/v7q4wobkzd091.png?width=2716&format=png&auto=webp&s=eb941eabfe69399ee95d7c7bb60c4a2b4d7c1034 https://preview.redd.it/70jairbkzd091.png?width=2880&format=png&auto=webp&s=a9ed1f280eca5bac029c4c7cbc56e9c4292f12ac submitted by /u/tomacdmota [link] [comments]
- Aurora Serverless v2 in Production?by /u/Mpjhorner (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 6:18 am
Is anyone using this at scale in production without issues? We are testing it at the moment with a production database and get random spikes stuck at 100% then it hangs and begins giving connections issues. As well as that we also get random drops outs. All of this same work load was running on a X-Large RDS instance prior with no issues. Support always saying this small issues etc. however I get the feeling it isn’t production ready. I know it’s new but it was pre-release for ages, hence giving it a try. What is your experience so far? submitted by /u/Mpjhorner [link] [comments]
- How can I federate users to AWS (SSO?) using LDAP or SCIM and then locking down CLI access with AWS-based MFA?by /u/xrscx (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 3:59 am
I have been doing some research and talking to support but I'm not exactly figuring out the solution for my use case. I want to federate users to AWS to be used across our AWS Org (AWS SSO?) via either LDAP or SCIM. However, we want to control MFA on the AWS side. That is, the federated user has MFA assigned inside of AWS and that they are not redirected to the IdP for MFA challenges. Largely, this is to put MFA on CLI access. Due to some factors of our environment, we cannot enforce MFA from there (to AWS CLI, at least). Any ideas on how to achieve this or if it is possible? Again, federate users to AWS and then enforce MFA on the user profiles that now live in AWS. Cost is a major factor as well. submitted by /u/xrscx [link] [comments]

- Difference between using X-Ray APM's with OTEL vs Meshby /u/araujobnelsong (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 19, 2022 at 1:21 am
Hello guys, So right now I have a Ruby application running in an EKS Cluster. We are currently using Datadog for tracing all our requests but it's has been asked to switch to AWS' X-Ray APM. I have been investigating and basically found 2 options to achieve this: 1) AWS Distro for OpenTelemetry : The site itself is a bit confusing but I think I'm understading it. If I'm right, I should follow those steps in my infrastructure: https://aws-otel.github.io/docs/setup/eks which basically guides you to install the OTEL collector as a sidepod (and also add a couple of lines in your application code) 2) Using Appmesh: Using the appmesh chart to EKS (which I already have configured) but passing some parameters such as : --set tracing.provider=x-ray -- The second one seems simple to do (considering I'm already using mesh) but maybe I'm missing something (?). Perhaps using the second way I wont be able to capture certain things, I don't know. Would be cool if anyone with some expertise on this can tell me the pros/cons of those 2 ways. Thanks in advanced. submitted by /u/araujobnelsong [link] [comments]
- Taking an Instructor-led Course After or Before Study Materials?by /u/g0stsec (AWS Certifications) on May 19, 2022 at 1:01 am
Looking for recommendations on this. Background: I'm an IT professional with 20 years experience. Experience up and down the OSI model from end user support, helpdesk and enterprise service management. Solid background in networking, network security, systems administration, (Linux and Windows), storage solutions, and some virtualization experience (VMWare ESXi specifically). Opportunity: I have an opportunity to take a 3 day instructor-led course to prepare for the Solution Architect Associate exam. I'm not under the impression that this instructor led course is all I need. I expect to study materials for several weeks. Would you recommend taking the course soon (in the next few weeks) then studying for weeks, or taking the course after studying for several weeks (based on your experience if you have it please). submitted by /u/g0stsec [link] [comments]

Hi everyone! I’m new to AWS certs but have some experience penetration testing AWS environments. I was thinking of doing AWS Solutions Architect Associate (with probably Cloud practitioner as part of my study) followed by AWS Security Specialist but I wasn’t sure if: a) there are any pre-requisites for the security specialist or if I could jump straight in b) if anyone has just jumped straight in to security specialist or if they any of the aforementioned certs (solutions architect and practitioner) are recommended.

I am just beginning to learn about EC2 in hopes to get the cloud practitioner certification. I am taking the essential course that is provided by Amazon. When talking about compute optimized instances it gives the example of dedicated gaming servers. I thought a dedicated server was one that you had in house. Wouldn’t using AWS mean it’s not a dedicated server? Or is it saying it would be just as good? Sorry if this is a dumb question, very new to cloud computing. submitted by /u/TheKwom [link] [comments]

Hey redditors, Is there a way for a data provider to enable subscribers to use a vendor provided license instead of the AWS Data Exchange subscription when subscribing to the individual products offers? My use case here is I want to distribute the data through multiple platforms and not just AWS Data Exchange. So ideally, I would want subscribers to use the license which could be generated by the customers/subscribers through my license portal and use this to allow/enable them to subscribe to the product offerings in AWS Data Exchange. This way I can then publish my data to some other platform say Azure Data Factory and the customer/subscriber would be able to use the same license to access the data there as well without having to create separate subscriptions on individual platforms. Is this possible to do? Or is there any workaround for this? submitted by /u/rox11goly [link] [comments]

- Hosting dotnet core web app in aws elasticbeanstalk with datadog.

Can any one help me with this noob question? I know this is more of a datadog question than aws question but was wondering if anyone here has some experience with datadog with elasticbeanstalk. I am trying to host a dotnet core web application in aws elasticbeastalk. Windows With IIS platform. And trying to collect traces from my web application to datadog. I was under the impression that we can have a dedicated datadog agent server and send all the traces to that agent. Is this right approach? or do I need to install datadog agent in each ec2(web servers). If dedicated server is ok. I created a dedicated server and installed the datadog agent but when I run telnet or powershell Test-NetConnection command to check connection to the server port 8126 it shows tcp connection failed.

I have a security group that whitelists RDP traffic for the range 184.108.40.206/16 A VDI was unable to connect, so the same RDP rule was added specifically for its IP (220.127.116.11/32) and that fixed the issue. Shouldn't the first rule cover this? The instance's IP is part of the CIDR but for some reason only listing it specifically has granted access. I'm thinking something else must have been changed but I do want to check if there would be any reason this change could have done it. submitted by /u/thekingofbeans42 [link] [comments]

Hey all, I'm having ECS assume roles and invoke lambdas in other trusted accounts in my AWS Org. To keep maintenance simple as this scales, I added a PolicyDocument to my ECS Task Role that allows lambda:InvokeFunction on resource * and sts:AssumeRole on resource *. Because the ECS Task role can only be assumed by the ECS service, I get the impression it's decently well secured and therefore not much of a weak link in our security. Am I missing something, do you think it's safe to allow this ECS task to assume any role or invoke any Lambda function? submitted by /u/RemarkableFlow [link] [comments]

- How I passed Certified Cloud Practitioner Exam by studying < 15 hours (Tips)by /u/Adventurous-Sign4520 (AWS Certifications) on May 18, 2022 at 1:47 pm
Hey everyone, I am writing this post to serve as a guide for folks who are looking for a quicker way to crack the exam. FYI, I have < 1 year AWS experience. Before I started my prep I was aware about high level basics for EC2, Lambda, SQS, SNS, RDS. I did Ultimate AWS Certified Cloud Practitioner - 2022 course by Stephne Maarek and skipped the hands on parts (you can do the hands-on if you are curious about something). I watched lectures at 1.25x and after end of every module, I would go through summary lecture and do the quizzes for the module. Before my exam, I went through all summary sections again and did all those practice quizzes again for each module. I appeared in the exam and surprisingly, everything that was asked was seen in the course. Just my two cents for people who are in a bit of a rush. Give yourself 2 days and schedule time blocks in calendar to study for the exam. Edit1: Create a document to remember high level summary of what each thing does. If instructor mentions something important (or something is highlighted in bold in the slides), put it in your notes. Take a minute to guess (or memorize) what the service does before instructor talks about it in the summary. I skipped Section 20: Other services as it was likely not going to be in the exam submitted by /u/Adventurous-Sign4520 [link] [comments]

So finally received my results today, thanks to everyone that posted his/her experience here doing the exam. I took it in a Test center (Person Vue) because of your recommendations and would 100% repeat the experience, flawless and the labs went smooth. Background: This is my second cert, last year got the Developer Associate and up today I've got around 2 years working with AWS, lately on personal projects for learning purpouses. Having experience with the console helps a ton with the labs, and doing such projects helped me grasping the knowledge better. I am a software developer with 5 years of exp. and I want to jump into Architect or Devops, that will depend on my new job. I used u/stephanemaarek udemy course and u/jon-bonso-tdojo practice exams/labs, studied for 2 and a half months 1 to 2 hours daily, and took a bunch of notes in the form of flashcards (around 900 flashcards), which I revised daily (10-100 cards per day). On practice tests I was scoring around 80%, I did the one in Mareek course and then the final exam in job bonso material, doing the exams in section mode and review mode helped me a lot to tackle the weak points, and the explanations of each answer are just amazing. I am going to focus now on skill development, so no certs for now but after I decide with path to go (probably devops) I'll go for Devops Pro. submitted by /u/nonFungibleHuman [link] [comments]

Hi everyone, just received my results, scored 705/1000. Which kinda sucks because it's so close to 720! (It's close, right? I'm not really too sure about the margins). Exam was on the 17th of May. I finished Stephane's course literally the day before. Didn't even attempt the practice test cuz well, to be honest, I didn't expect the course to have SO much content. All I did was review the quizes at the end of each chapter and did the 10 free questions off the AWS website. I wished I'd found this sub sooner, seeing that there are so much helpful content, like tutorials dojo practice exams (which I hear is really helpful). Am gonna take a few days off and then booking another test date to try again. Also, is the retest 50% off? My first attempt was FOC via a voucher my company. -Edit- Thanks for the tips and encouragement guys!

- AWS, I love your services and APIs but your API/SDK/CLI docs are killin' me!by /u/YeNerdLifeChoseMe (Amazon Web Services (AWS): S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, VPC and more) on May 17, 2022 at 8:21 pm
I can't be the only one feeling this. I love AWS APIs. I love the services. But the API/SDK/CLI docs are soooo painful to navigate. I've written my own doc search helper for CLI/API that helps me get around. I’m going to have to write something else to help with the boto3 AWS python SDK. I think it’s even more painful than the CLI docs. A common problem with the docs is that you have this big table of contents on the left so you click on a topic, and it bring up a page and possibly to an anchor, but the page is huuuuuuge and there’s often no hyperlinks to get around easily, so you have to search. Here’s an example: IAM — Boto3 Docs 1.23.1 documentation (amazonaws.com). When you click on that link you go to the IAM service Policy resource about 4/5 down a web page that goes on for miles. The table of contents isn’t synced. And the only way to navigate is to search or Ctrl-Home and there’s a slightly more focused TOC than the left frame. There's other "mini-TOCs" scattered throughout the page. So instead of just complaining with no solution, here’s what I think would help on most of the documentation: Have the TOC on the left frame be hierarchical and context sensitive. So you can expand/collapse sections with a useful search that stays visible when you scroll. Break up the content on the right frame into much smaller pages Have more hyperlinks in the content Microsoft actually does an excellent job. Here’s an example: SmtpClient Class (System.Net.Mail) | Microsoft Docs I spend all day doing AWS, and I love it, so this isn't just spewing hate. This is simply a daily pain point for me and I can imagine it is for many others as well. EDIT: To clarify, the docs are complete and well written. Just really painful to navigate. I know the docs are open source and I can help fix it, but AWS isn't a charity and I spend my entire days working on stuff that ultimately AWS gets paid for. I think they have the resources to handle this. I'm not a big complainer, but this is a really valid source of pain for me each day. I would literally be twice as productive if the docs were easier to navigate. I know software and systems development. I don't know the syntax to every API and the attributes of every model. The reality this is the world we live in. Things change so quickly. Kudos to AWS for keeping the documentation up to date. It's to their benefit. It would also be to their benefit to update their documentation frameworks on the development side. This isn't an open source or academic project. It's the largest for-profit cloud provider in the world. submitted by /u/YeNerdLifeChoseMe [link] [comments]

- SAA-C02 Passby /u/sdotIT (AWS Certifications) on May 17, 2022 at 11:53 am
Studied for 2 months. I had some complicated personal stuff going on and probably would have cut that down a bit had I not. Finished with a 796. Took the exam at home with Pearson. Woke up very ill and it was quite difficult to focus on the exam. I paid for it so I wasn't going to not take it. Finished with 50 minutes left. Tried to go through some questions but after a few minutes of that I wrapped the exam. Couldn't stand sitting there any longer and needed to lay down. Used Adrian Cantrill's course and Tutorial Dojos practice exams. All you need, really. I took 2 pages of notes. I'm not a big note taker and only really did so to reinforce facts. I also had Stephane Maareks udemy course from before I knew about Adrian's (months before I started studying). I used this in lieu of notes. Used the short videos to brush up on things I needed to from practice exam results. If I felt I needed more I rewatched Adrian's video on it. Went through his slides twice, once a week before and once the day of. I had some wild questions on the exam regarding Polly, Lake Formation, and Code Pipeline. Roughly 70% of the exam I feel like was based on databases and decoupling. I felt ready. I feel I should have done better. I don't think my not feeling well played much if any role in my score. Some of the questions were worded very confusingly. Much more than other certs I've taken or the tutorial dojo practice ones. I feel the exam was quite a bit more difficult than the practice exams. I scored 65% on the first two practice exams, 73% on the third, and 80%+ on the rest. Each time following first two, brushing up on things I missed (was noting down topics as I went through answers so I had a list of topics to go through). Happy to answer any questions! submitted by /u/sdotIT [link] [comments]
- Landed a jr. SA role with <1 yr experience. Let's talkby /u/keypairvalue (AWS Certifications) on May 17, 2022 at 11:27 am
Questions are preferred, I don't think I can type out a wall of text that is going to help everyone in their specific situations. I achieved the SAA and SAP in a span of 7 months. I got my SAA while not in tech, SAP while working a tech job. My first and only job thus far was non-technical monitoring in a NOC team at a VAR. I was promoted to jr. SA internally. A big contributing factor to landing that first job, imo is that I researched companies before deciding to apply to them. I didn't spend entire days sending out resumes/applying. My criteria for the companies I was looking to apply to were: MSP/VAR. Generally agreed upon as fast-paced and stressful in a lot of departments, but having many different clients and problems to solve is a great learning experience. They also tend to hire like crazy. Numerous cloud roles available, especially junior/associate level ones even if they weren't the specific role I was looking for. Companies may have opportunities that aren't necessarily posted on their job boards. I wasn't going to be picky, I was OK with working my way up in a company to get that breakthrough. A big plus if providing cloud solutions was a relatively new thing for them As for the interview I could write pages on it. In short, me being super fresh & having the SA Pro clearly threw up some doubt/red flags in the interviewer's mind. He made sure I had the practical knowledge to go along with it. Big emphasis on practical, as more often than not, people unfortunately don't come out with practical knowledge after passing a cert. Which can make these interviews go from tough, to actually impossible. Also the dude who made a throwaway to just say I exam-dumped it on my last post, can suck my nuts. You need to have a plan.. it's tough being new to tech and picking out an end-goal, but it's the most optimal way to climb quick. Lay out your steps. Your certs, projects, & technical skills need to paint a clear picture of where you're going. All my certs, projects, and skills.. they're all architecture related. As for my future - I'm getting more engineering experience since a full-fledged SA is expected to handle low-level technical implementations to a degree, but also plan around the nuances of that. submitted by /u/keypairvalue [link] [comments]
- Is it normal to feel super confused after the first day of studying for a Cloud practitionerby /u/FlimsyParty544 (AWS Certifications) on May 17, 2022 at 4:26 am
I'm a musician looking to dive into the tech side of music. A friend of mine suggested I go get my AWS cloud practitioner then solutions and get an entry-level job and work my way up in the industry. I'm using A cloud guru to help study but after going through units one and 2 I feel kind of lost. Is this a normal feeling to have? submitted by /u/FlimsyParty544 [link] [comments]
- Prepping for SysOps Admin, Practice Lab Walkthrough Videosby /u/JBizzle703 (AWS Certifications) on May 17, 2022 at 1:16 am
I've been prepping for the SysOps Admin Associate exam (primarily using ExamPro as the study content), but have started to make some lab walkthrough videos of some of the core technical components. I wanted to share my latest one here on Auto Scaling and Load Balancing, in case it might help some folks studying for this or the SAA. If you like it, I have a few more on the channel I've done (VPC's/Networking, Cloudformation, and S3 and lifecycle polices). https://youtu.be/RBKNVhAD6bw submitted by /u/JBizzle703 [link] [comments]
- Passed AWS Certified Developer - Associate (CDA)by /u/Account_Aged_Well (AWS Certifications) on May 16, 2022 at 7:21 pm
Last Saturday I took and passed the AWS Certified Developer Associate (CDA) certification exam. Woohoot! Just want to share the achievement with the group. I credit two things for passing: my current role and Tutorials Dojo practice exams on Udemy. For the latter, I would take an exam and then build flashcards from what I didn't know. Then it was spaced repetition until memorized. At my current role as a Software Developer working the full stack I deal with AWS on a daily basis. I've been in the profession for two years, so this helped out a bunch as well. submitted by /u/Account_Aged_Well [link] [comments]

- Failed SAA-C02by /u/Guilty-Owl-9625 (AWS Certifications) on May 16, 2022 at 1:24 pm
Took the test Sunday and Got my score today. I failed the SAA-C02 (705). Totally bummed. I’m looking for recommendations on what I can do to pass the SAA-C02. I completed the Stephen Maarek Udemy course and the tutorialsdojo practice tests by Jon Bonso. Apparently this isn’t enough. Do I sign up for Cantrill’s course or do I more practice tests? submitted by /u/Guilty-Owl-9625 [link] [comments]
