Amazon Elastic Container Services (Amazon ECS) provides a Cluster Auto Scaling (CAS) capability to dynamically manage the scaling of your Amazon Elastic Compute Cloud (EC2) Auto Scaling groups (ASG) on your behalf, so that you can focus on running your containers. Capacity Providers is the compute interface that links your Amazon ECS cluster with your ASG. With Capacity Providers, you can define flexible rules for how containerized workloads run on different types of compute capacity, and manage the scaling of the capacity. Capacity Providers improve the availability, scalability, and cost of running tasks and services on ECS. Starting today, we are simplifying the integration mechanism between Capacity Providers and ASGs by directly integrating with target-tracking scaling policy instead of relying on AWS Auto Scaling scaling plan.

This course gives a great foundation and makes sense of the other content you encounter later. Make flashcards/notes using Save All. This is an excellent flashcard/notes app where you can paste in pure information, and Save All automatically turns it into interactive quizzes. It’s speedy to add notes to Save All, so you can type in while watching the video course. I recommend memorizing all the non-technical information you can. The best way to do this is to do Save All quizzes every day. Start doing quizzes from the first day of watching the course to take advantage of the spacing effect (summary: you remember more if you leave gaps between studying). If you quiz every day, you won't have to do any cramming by the time you get to the practice exams. Use the free cheat sheets from digital cloud. I also added these to Save All. These cheat sheets will allow you to catch anything you have missed or misunderstood from the video course. Do some free practice exams. It’s essential to do practice tests to see how the questions are structured and cover any topics you have missed so far. Here are a few: youtube, itexams, testprep training. Finally do the free course and practice test provided by AWS training. You will know most of it by this point to speed through it, but make sure you note down to cover any services you don’t know about yet.

I am trying to understand the following question (from Stephane's course): ​ ​ https://preview.redd.it/gkh4ip142m191.png?width=1446&format=png&auto=webp&s=239628b47e59f3fe81a77182249bacd88acca9fb I do not understand why the answer is 172.16.0.0/16 ​ /16 because that is the maximum subnet mask allowable in VPC, but why 172.16.0.0 specifically? Is it because the only "possible" remaining answer 10.0.16.0/16 is already used in the question (10.0.0.0/8)? ​ Thank you for taking the time to help me! submitted by /u/butrimodre [link] [comments]

I just took the AWS Certified Solutions Architect and after completing the survey there were no notifications on whether I passed or failed.

Anyone ever experienced this and can give some insights please? submitted by /u/ewmn69 [link] [comments]

I took the SAA this pass Saturday. Im 100% sure I failed. I got an email from credly saying "I have a certificate to claim." I 100% thought it was a scam. Today (2 days later) I decided to look up the company and the email. I felt at that point it was legit, maybe they have a paid service and got my name from aws. Its saying I have my SAA certification. Im confused because I knew that I couldn't passed. Not even close. So I figured I would wait for my results after 5 business days from AWS. Is this legit? submitted by /u/kai_zen_kid [link] [comments]

Today, Amazon EC2 announced the Stop Protection feature that enables customers to protect their instances from accidental stop actions. Previously, customers could protect their instances from unintentional terminate actions by enabling Termination Protection. With Stop Protection, customers with stateful workloads can safeguard data in instance store volume(s) from unintentional stop and terminate actions.

Amazon Managed Grafana now supports a new API for creating Grafana API tokens, as well as support for new plugins, Grafana version 8.4, and workspace tags. With CreateWorkspaceApiKey, customers can create Grafana API tokens without having to log into the Grafana workspace console, enabling users to programmatically create, delete, and manage Grafana resources such as dashboards, alerts, and data sources.

Tags are labels in the form of key-value pairs that may be attached to Amazon Managed Grafana workspaces to search, filter, or allocate costs.

I’ve read all over Reddit that people say the information while studying for the SAA also applies to the CCP. At what point should I (or anyone else studying for the SAA) — take the CCP if the study material we have is for the SAA? submitted by /u/JohnniNeutron [link] [comments]

Hi all! I hope you're having a good week. I passed the AWS DEV Associate certificate 20 days ago, and now I want to pursue the AWS Solution Architect (Associate) as well (I took it in the past, but it expired) I was wondering, anyone has an updated list/info of the differences/new stuff I need to study? I know I can take the AWS SA course and just "ignore" or don't pay a lot of attention to the repeating topics, but maybe there's a clear list of topics I can use as a guideline. Thank you! submitted by /u/andreal [link] [comments]

Has anyone taken the CCP after the SAA? I unfortunately have to take this cert as well for my company to meet the Select Tier requirement. Tips and reccomendations welcome! submitted by /u/hershuteezem [link] [comments]

Amazon Personalize now provides offline model metrics for recommenders enabling you to evaluate the quality of recommendations. A recommender is a resource that provides recommendations optimized for specific use cases, such as “Frequently bought together” for Retail and “Top picks for you” for Media and Entertainment. Offline metrics are metrics that Amazon Personalize generates when you create a recommender. You can use offline metrics to analyze the performance of the recommender's underlying model. Offline metrics allow you to compare the model with other models trained on the same data. The metrics provided include coverage, mean reciprocal rank, normalized discounted cumulative gain (NDCG) and precision.

So I was alone in my room to be honest and has no other person in room. I show the proctor my whole room before starting exam. I was giving my aws cloud practitioner exam. When I was middle of exam i get a text in chat option that I am talking but I was not maybe I just opened my mouth for only a second to adjust my facial expression like everyone do. Instantly i tried to reply him back with the chat option so I can explain him but my message wasn't sending even after hitting enter many times. And then again he send he message out of nowhere and told me that he filed a case against me and again I was unable to send them message so I can convince them. And then proctor close my window, then i hurry to go to website of Pearson and do the chat with their employee and he told me that you will get email within a week regarding the case. I don't get email rn when I am writing this. Does anyone have same experience like me and know what will happen. Do i allowed to retake the exam or get a refund? submitted by /u/godcombat [link] [comments]

Does the voucher given after completing the first certification exam expire? If so, how long do they usually last for? submitted by /u/butrimodre [link] [comments]

I read all negative criticism in the sub, but decided to buy it anyway. It was a conscious decision after considering how my brain and motivation work and also reading positive criticism and recommendations. I would like to ask experienced subscribers of this platform for hints about how to make the best use of it. I believe it has more course hours than I can spend in one year in my limited spare time. My goal is acquire skills in AWS/container orchestration technologies, but also become certified. submitted by /u/matusaleeem [link] [comments]

Hi Anyone can help me understand why S3 is the best solution.Does S3 supports key value storing data? ​ https://preview.redd.it/9p5ohumkoc191.png?width=803&format=png&auto=webp&s=d5c6c92dbe01f07208fd0efacd1f36ce1417d540 submitted by /u/KeyCup2606 [link] [comments]

First of all, I want to thank u/acantril for his awesome in depth SAA-C02 course. I learned so much from it and still have so far to go to understand to the level that I want to be at. I also want to thank u/jon-bonso-tdojo for the practice tests. The explanations and exam simulator are truly invaluable for getting a feel for the exam style and types of questions. I passed CCP back in July 2020. I bought Adrian’s SAA-C02 course a couple months later and started going through it. I had several times that I stopped and had long gaps between studying and would lose everything I had just learned and needed to keep starting over. Then I quit for several months. I finally got back into it at the beginning of 2022. Took a few breaks like before but not as long in between. I scheduled the exam for March 20. I was nowhere near ready and rescheduled for April 20. Still, was nowhere close to being done with the course or taken any practice exam. I rescheduled again to May 20 telling myself I am taking it that day no matter what. Of course I wait until the last ten days to really get going. I went through probably 70% of the course in that ten day span. I would highly recommend not doing this. It was way too much and hard to retain in the short amount of time. I took one TD quiz and got a 63. I took one TD test and got a 76. I felt decent after that but not great. Brushed up on a few things. Then said this is it. Let’s go! I can’t reschedule now as it’s within 24 hours. I thought the test was way more difficult than the practice exams. But then again I did not do myself any favors by going at it the way I did. I only answered probably five of the first 30 questions I read. I had to keep telling myself to not get discouraged and keep moving forward. Plenty of time to go back and review flagged questions. I got down to 15 minutes left in my exam and still had many questions to go through and answer that I flagged. Some I flagged as they were just really long and others that I wasn’t sure and would revisit later. It was then that my exam crashed with a 502 - Bad Gateway error and someone from the test center had to log me back in. It thankfully resumed from where I was. I finished my last question with less than two minutes on the time remaining and thought this is it, it’s not going to get any better to read anymore questions and second guess myself. I had a lot of database, ASG, kinesis, SQS, DX, and VPN questions. Lots of most cost effective, most reliable, most highly available, etc. You really have to read carefully and know what the question is asking for as there could be several potentially correct answers, but might not be exactly what they are looking for. It was really difficult and I thought I for sure failed. Of course I did not see a pass/fail when I submitted the test. It just stated that the test result has been saved and I would see the results in up to five business days and to check my account. I took it on Friday, got nothing until this morning that I passed. The wait was brutal but since I thought I failed, it was a pleasant surprise to wake up to the badge from Credly in my inbox! All I can say is, don’t procrastinate and don’t schedule the exam until you’re ready. Having a deadline is cool but it’s not all about the exam. Learn the material in depth and the exam will be an afterthought. I now need to go back and learn it more in depth if I want to have any chance at sysops or SA Pro. I think one of those will be next. Then azure is also in the near future. Hope this helps someone as I’ve gotten so much advice and helpful knowledge from this sub. Good luck to anyone else taking the exam!!! submitted by /u/sysadmin_402 [link] [comments]
