Latest Cloud AWS Cloud Training Questions and Answers from around the Web:
-
How do I set up Failover on Amazon AWS Route53? In simple configurations, you create a group of records that all have the same name and type, such as a group of weighted records with a type of A for example.com. In more complex configurations, you create a tree of records that route traffic based on multiple criteria. Read more …
-
I assume it is your subscription where the VPCs are located, otherwise you can’t really discover the information you are looking for. On the EC2 server you could use AWS CLI or Powershell based scripts that query the IP information. Based on IP you can find out what instance uses the network interface, what security groups are tied to it and in which VPC the instance is hosted. Read more here…
- What are some tips, tricks and gotchas when using AWS Lambda to connect to a VPC? When using AWS Lambda inside your VPC, your Lambda function will be allocated private IP addresses, and only private IP addresses, from your specified subnets. This means that you must ensure that your specified subnets have enough free address space for your Lambda function to scale up to. Each simultaneous invocation needs its own IP. Read more here…
When a Lambda “is in a VPC”, it really means that its attached Elastic Network Interface is the customer’s VPC and not the hidden VPC that AWS manages for Lambda.
The ENI is not related to the AWS Lambda management system that does the invocation (the data plane mentioned here). The AWS Step Function system can go ahead and invoke the Lambda through the API, and the network request for that can pass through the underlying VPC and host infrastructure.
Those Lambdas in turn can invoke other Lambda directly through the API, or more commonly by decoupling them, such as through Amazon SQS used as a trigger. Read more ….
5. How do I invoke an AWS Lambda function programmatically?
public InvokeResult invoke(InvokeRequest request)
Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event.
For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace.
When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior.
For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.
The status code in the API response doesn’t reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors, or issues with your function’s code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level ( ConcurrentInvocationLimitExceeded) or function level ( ReservedFunctionConcurrentInvocationLimitExceeded).
For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.
This operation requires permission for the lambda:InvokeFunction action. Read more…
Default VPC
- 1 per region
- a set VPC CIDR range … you can’t changed it
- has everything configured by default .. 1 subnet per AZ, an internet gateway, routes and subnets set to allocate IPv4 by default.
Custom VPCs
- As any as you want per region (within limits)
- Customisable CIDR range
- Customisable subnet structure
- Nothing configured by default, you have to configure everything
The subnet mask determines how many bits of the network address are relevant (and thus indirectly the size of the network block in terms of how many host addresses are available) –
192.0.2.0, subnet mask 255.255.255.0 means that 192.0.2 is the significant portion of the network number, and that there 8 bits left for host addresses (i.e. 192.0.2.0 thru 192.0.2.255)
192.0.2.0, subnet mask 255.255.255.128 means that 192.0.2.0 is the significant portion of the network number (first three octets and the most significant bit of the last octet), and that there 7 bits left for host addresses (i.e. 192.0.2.0 thru 192.0.2.127)
When in doubt, envision the network number and subnet mask in base 2 (i.e. binary) and it will become much clearer. Read more here…
IAM is the new perimeter.
Separate out the roles needed to do each job. (Assuming this is a corporate environment)
Have a role for EC2, another for Networking, another for IAM.
Everyone should not be admin. Everyone should not be able to add/remove IGW’s, NAT gateways, alter security groups and NACLS, or setup peering connections.
Also, another thing… lock down full internet access. Limit to what is needed and that’s it. Read more here….
Within a single VPC, the subnets’ route tables need to point to each other. This will already work without additional routes because VPC sets up the local target to point to the VPC subnet.
Security groups are not used here since they are attached to instances, and not networks.
See: Amazon Virtual Private Cloud
The NAT EC2 instance (server), or AWS-provided NAT gateway is necessary only if the private subnet internal addresses need to make outbound connections. The NAT will translate the private subnet internal addresses to the public subnet internal addresses, and the AWS VPC Internet Gateway will translate these to external IP addresses, which can then go out to the Internet. Read more here ….
12. What are the applications (or workloads) that cannot be migrated on to cloud (AWS or Azure or GCP)?
A good example of workloads that currently are not in public clouds are mobile and fixed core telecom networks for tier 1 service providers. This is despite the fact that these core networks are increasingly software based and have largely been decoupled from the hardware. There are a number of reasons for this such as the public cloud providers such as Azure and AWS do not offer the guaranteed availability required by telecom networks. These networks require 99.999% availability and is typically referred to as telecom grade.
The regulatory environment frequently restricts hosting of subscriber data outside the of the operators data centers or in another country and key network functions such as lawful interception cannot contractually be hosted off-prem. Read more here….
13. How many CIDRs can we add to my own created VPC?
You can add up to 5 IPv4 CIDR blocks, or 1 IPv6 block per VPC. You can further segment the network by utilizing up to 200 subnets per VPC. Amazon VPC Limits. Read more …
14. Why can’t a subnet’s CIDR be changed once it has been assigned?
Sure it can, but you’ll need to coordinate with the neigbours. You can merge two /25’s into a single /24 quite effortlessly if you control the entire range it covers. In practice you’ll see many tiny allocations in public IPv4 space, like /29’s and even smaller. Those are all assigned to different people. If you want to do a big shuffle there, you have a lot of coordinating to do.. or accept the fallout from the breakage you cause. Read more…
15. Can one VPC talk to another VPC?
16. What questions to expect in cloud support engineer deployment roles at AWS?
Cloud Support Engineer (CSE) is a role which requires the following abilities:
- Wide range of technical skills
- Good communication and time management
- Good knowledge about the AWS services, and how to leverage them to solve simple to complex problems.
As your question is related to the deployment Pod, you will probably be asked about deployment methods (A/B testing like blue-green deployment) as well as pipelining strategies. You might be asked during this interview to reason about a simple task and to code it (like parsing a log file). Also review the TCP/IP stack in-depth as well as the tools to troubleshoot it for the networking round. You will eventually have some Linux questions, the range of questions can vary from common CLI tools to Linux internals like signals / syscalls / file descriptors and so on.
Last but not least the Leadership principles, I can only suggest you to prepare a story for each of them. You will quickly find what LP they are looking for and would be able to give the right signal to your interviewer.
Finally, remember that theres a debrief after the (usually 5) stages of your on site interview, and more senior and convincing interviewers tend to defend their vote so don’t screw up with them.
Be natural, focus on the question details and ask for confirmation, be cool but not too much. At the end of the day, remember that your job will be to understand customer issues and provide a solution, so treat your interviewers as if they were customers and they will see a successful CSE in you, be reassured and give you the job.
Expect questions on cloudformations, Teraform, Aws ec2/rds and stack related questions.
Its a high tech call center. You are expected to take calls, chats of customers and give them technical advice. You will not be doing any of the cool stuff you did earlier (if you are coming from engineering job or DBA). You will surely gain a very good knowledge of multiple AWS services and the one that you will be hired in, however most of the knowledge will be theoretical and nothing practical in day-to-day life.
It also depends on the support team you are being hired for. Networking or compute teams (Ec2) have different interview patterns vs database or big data support.
In any case, basics of OS, networking are critical to the interview. If you have a phone screen, we will be looking for basic/semi advance skills of these and your speciality. For example if you mention Oracle in your resume and you are interviewing for the database team, expect a flurry of those questions.
Other important aspect is the Amazon leadership principles. Half of your interview is based on LPs. If you fail to have scenarios where you do not demonstrate our LPs, you cannot expect to work here even though your technical skills are above average (Having extraordinary skills is a different thing).
The overall interview itself will have 1 phone screen if you are interviewing in the US and 1–2 if outside US. The onsite loop will be 4 rounds , 2 of which are technical (again divided into OS and networking and the specific speciality of the team you are interviewing for ) and 2 of them are leadership principles where we test your soft skills and management skills as they are very important in this job. You need to have a strong view point, disagree if it seems valid to do so, empathy and be a team player while showing the ability to pull off things individually as well. These skills will be critical for cracking LP interviews.
You will NOT be asked to code or write queries as its not part of the job, so you can concentrate on the theoretical part of the subject and also your resume. We will grill you on topics mentioned on your resume to start with.
17. Traditional monolithic architectures are hard to scale: TRUE
Monolithic architecture is something that build from single piece of material, historically from rock. Monolith term normally use for object made from single large piece of material.” – Non-Technical Definition. “Monolithic application has single code base with multiple modules.
Large Monolithic code-base (often spaghetti code) puts immense cognitive complexity on the developer’s head. As a result, the development velocity is poor. Granular scaling (i.e., scaling part of the application) is not possible. Polyglot programming or polyglot database is challenging.
Drawbacks of Monolithic Architecture
This simple approach has a limitation in size and complexity. Application is too large and complex to fully understand and made changes fast and correctly. The size of the application can slow down the start-up time. You must redeploy the entire application on each update.
18. Sticky Sessions help increase your application’s scability: FALSE
Sticky sessions, also known as session affinity, allow you to route a site user to the particular web server that is managing that individual user’s session. The session’s validity can be determined by a number of methods, including a client-side cookies or via configurable duration parameters that can be set at the load balancer which routes requests to the web servers.
Some advantages with utilizing sticky sessions are that it’s cost effective due to the fact you are storing sessions on the same web servers running your applications and that retrieval of those sessions is generally fast because it eliminates network latency. A drawback for using storing sessions on an individual node is that in the event of a failure, you are likely to lose the sessions that were resident on the failed node. In addition, in the event the number of your web servers change, for example a scale-up scenario, it’s possible that the traffic may be unequally spread across the web servers as active sessions may exist on particular servers. If not mitigated properly, this can hinder the scalability of your applications. Read more here …
19. AWS recommends replicating across Availability Zones for resiliency: TRUE
If you need to replicate your data or applications in an AWS Local Zone, AWS recommends that you use one of the following zones as the failover zone:
-
Another Local Zone
-
An Availability Zone in the Region that is not the parent zone. You can use the describe-availability-zones command to view the parent zone.
For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure.
20. What are the benefits of AWS Cloud Computing?
- Trade Capital expenses for variable expenses
- Increase speed and agility
- Benefit from massive economies at scale
- Stop spending money on running and maintaining data centers
- Stop guessing capacity
- Go global in minutes
21. What is the default behavior for an EC2 instance when terminated?
After you terminate an instance, it remains visible in the console for a short while, and then the entry is automatically deleted. You cannot delete the terminated instance entry yourself. After an instance is terminated, resources such as tags and volumes are gradually disassociated from the instance, therefore may no longer be visible on the terminated instance after a short while.
When an instance terminates, the data on any instance store volumes associated with that instance is deleted.
By default, Amazon EBS root device volumes are automatically deleted when the instance terminates. However, by default, any additional EBS volumes that you attach at launch, or any EBS volumes that you attach to an existing instance persist even after the instance terminates. This behavior is controlled by the volume’s DeleteOnTermination attribute, which you can modify
For more information, please visit: Terminate Your Instance
22. How do Amazon EC2 EBS burst credits work?
The documentation on General Purpose SSD (gp2) EBS volumes can be found at this page: New SSD-Backed Elastic Block Storage
When you first launch an instance with gp2 volumes attached, you get an initial burst credit allowing for up to 30 minutes of 3,000 iops/sec.
After the first 30 minutes, your volume will accrue credits as follows (taken directly from AWS documentation):
Within the General Purpose (SSD) implementation is a Token Bucket model that works as follows
- Each token represents an “I/O credit” that pays for one read or one write.
- A bucket is associated with each General Purpose (SSD) volume, and can hold up to 5.4 million tokens.
- Tokens accumulate at a rate of 3 per configured GB per second, up to the capacity of the bucket.
- Tokens can be spent at up to 3000 per second per volume.
- The baseline performance of the volume is equal to the rate at which tokens are accumulated — 3 IOPS per GB per second.
In addition to this, gp2 volumes provide baseline performance of 3 iops per Gb, up to 1Tb (3000 iops). Volumes larger than 1Tb no longer work on the credit system, as they already provide a baseline of 3000 iops. Gp2 volumes have a cap of 10,000 iops regardless of the volume size (so the iops max out for volumes larger than 3.3Tb)
23. Is elastic IP service free if we associate it with any VM (EC2 server)?
Elastic IP addresses are free when you have them assigned to an instance, feel free to use one! Elastic IPs get disassociated when you stop an instance, so you will get charged in the mean time. The benefit is that you get to keep that IP allocated to your account though, instead of losing it like any other. Once you start the instance you just re-associate it back and you have your old IP again.
Here are the changes associated with the use of Elastic IP addresses
No cost for Elastic IP addresses while in use
* $0.01 per non-attached Elastic IP address per complete hour
* $0.00 per Elastic IP address remap – first 100 remaps / month
* $0.10 per Elastic IP address remap – additional remap / month over 100
If you require any additional information about pricing please reference the link below
Amazon EC2 Pricing – Amazon Web Services
The other cost are as outlined in the paragraph you have quoted.
24. How do I reduce my AWS EC2 cost? My AWS EC2 expenditure comprises 80% of my AWS bill.
The short answer to reducing your AWS EC2 costs – turn off your instances when you don’t need them.
Your AWS bill is just like any other utility bill, you get charged for however much you used that month. Don’t make the mistake of leaving your instances on 24/7 if you’re only using them during certain days and times (ex. Monday – Friday, 9 to 5).
To automatically start and stop your instances, AWS offers an “EC2 scheduler” solution. A better option would be a cloud cost management tool that not only stops and starts your instances automatically, but also tracks your usage and makes sizing recommendations to optimize your cloud costs and maximize your time and savings.
You could potentially save money using Reserved Instances. But, in non-production environments such as dev, test, QA, and training, Reserved Instances are not your best bet. Why is this the case? These environments are less predictable; you may not know how many instances you need and when you will need them, so it’s better to not waste spend on these usage charges. Instead, schedule such instances (preferably using ParkMyCloud). Scheduling instances to be only up 12 hours per day on weekdays will save you 65% – better than all but the most restrictive 3-year RIs!
You can also save money with:
- Spot Instances
- AWS Dedicated Hosts & Dedicated Instances
- Auto Scaling Groups
- Rightsizing
25. What is the difference between an Instance, AMI and Snaphots in AWS? What are they used for?
Well AWS is a web service provider which offers a set of services related to compute, storage, database, network and more to help the business scale and grow
All your concerns are related to AWS EC2 instance, so let me start with an instance
Instance:
- An EC2 instance is similar to a server where you can host your websites or applications to make it available Globally
- It is highly scalable and works on the pay-as-you-go model
- You can increase or decrease the capacity of these instances as per the requirement
AMI:
- AMI provides the information required to launch the EC2 instance
- AMI includes the pre-configured templates of the operating system that runs on the AWS
- Users can launch multiple instances with the same configuration from a single AMI
Snapshot:
- Snapshots are the incremental backups for the Amazon EBS
- Data in the EBS are stored in S3 by taking point-to-time snapshots
- Unique data are only deleted when a snapshot is deleted
- Multiple EBS can be created using these snapshots
26. What are the main differences between a VPNs, VPS and VPC?
They are definitely all chalk and cheese to one another.
A VPN (Virtual Private Network) is essentially an encrypted “channel” connecting two networks, or a machine to a network, generally over the public internet.
A VPS (Virtual Private Server) is a rented virtual machine running on someone else’s hardware. AWS EC2 can be thought of as a VPS, but the term is usually used to describe low-cost products offered by lots of other hosting companies.
A VPC (Virtual Private Cloud) is a virtual network in AWS (Amazon Web Services). It can be divided into private and public subnets, have custom routing rules, have internal connections to other VPCs, etc. EC2 instances and other resources are placed in VPCs similarly to how physical data centers have operated for a very long time.
27. What is the use of elastic IP in AWS?
Elastic IP address is basically the static IP (IPv4) address that you can allocate to your resources.
Now, in case that you allocate IP to the resource (and the resource is running), you are not charged anything. On the other hand, if you create Elastic IP, but you do not allocate it to the resource (or the resource is not running), then you are charged some amount (should be around $0.005 per hour if I remember correctly)
Additional info about these:
You are limited to 5 Elastic IP addresses per region. If you require more than that, you can contact AWS support with a request for additional addresses. You need to have a good reason in order to be approved because IPv4 addresses are becoming a scarce resource.
In general, you should be good without Elastic IPs for most of the use-cases (as every EC2 instance has its own public IP, and you can use load balancers, as well as map most of the resources via Route 53).
One of the use-cases that I’ve seen where my client is using Elastic IP is to make it easier for him to access specific EC2 instance via RDP, as well as do deployment through Visual Studio, as he targets the Elastic IP, and thus does not have to watch for any changes in public IP (in case of stopping or rebooting).
28. Why would you choose not to use AWS Transit Gateway instead of VPC peering?
At this time, AWS Transit Gateway does not support inter region attachments. The transit gateway and the attached VPCs must be in the same region. VPC peering supports inter region peering.
29. Difference between AWS Workspace and AWS Ec2 VM?
- The EC2 instance is server instance whilst a Workspace is windows desktop instance
-
Both Windows Server and Windows workstation editions have desktops. Windows Server Core doesn’t not (and AWS doesn’t have an AMI for Windows Server Core that I could find).
-
It is possible to SSH into a Windows instance – this is done on port 22. You would not see a desktop when using SSH if you had enabled it. It is not enabled by default.
-
If you are seeing a desktop, I believe you’re “RDPing” to the Windows instance. This is done with the RDP protocol on port 3389.
- Two different protocols and two different ports.
- Workspaces doesn’t allow terminal or ssh services by default. You need to use Workspace client. You still can enable RDP or/and SSH but this is not recommended.
- Workspaces is a managed desktop service. AWS is taking care of pre-build AMIs, software licenses, joining to domain, scaling etc.
- What is Amazon EC2? Scalable, pay-as-you-go compute capacity in the cloud. Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
- What is Amazon WorkSpaces? Easily provision cloud-based desktops that allow end-users to access applications and resources. With a few clicks in the AWS Management Console, customers can provision a high-quality desktop experience for any number of users at a cost that is highly competitive with traditional desktops and half the cost of most virtual desktop infrastructure (VDI) solutions. End-users can access the documents, applications and resources they need with the device of their choice, including laptops, iPad, Kindle Fire, or Android tablets.
- Amazon EC2 can be classified as a tool in the “Cloud Hosting” category, while Amazon WorkSpaces is grouped under “Virtual Desktop”.
-
Some of the features offered by Amazon EC2 are:
- Elastic – Amazon EC2 enables you to increase or decrease capacity within minutes, not hours or days. You can commission one, hundreds or even thousands of server instances simultaneously.
- Completely Controlled – You have complete control of your instances. You have root access to each one, and you can interact with them as you would any machine.
- Flexible – You have the choice of multiple instance types, operating systems, and software packages. Amazon EC2 allows you to select a configuration of memory, CPU, instance storage, and the boot partition size that is optimal for your choice of operating system and application.
On the other hand, Amazon WorkSpaces provides the following key features:
- Support Multiple Devices- Users can access their Amazon WorkSpaces using their choice of device, such as a laptop computer (Mac OS or Windows), iPad, Kindle Fire, or Android tablet.
- Keep Your Data Secure and Available- Amazon WorkSpaces provides each user with access to persistent storage in the AWS cloud. When users access their desktops using Amazon WorkSpaces, you control whether your corporate data is stored on multiple client devices, helping you keep your data secure.
- Choose the Hardware and Software you need- Amazon WorkSpaces offers a choice of bundles providing different amounts of CPU, memory, and storage so you can match your Amazon WorkSpaces to your requirements. Amazon WorkSpaces offers preinstalled applications (including Microsoft Office) or you can bring your own licensed software.
