Exam AWS Certified Solutions Architect - Professional topic 1 question 892 discussion

Here is a good reference material: https://aws.amazon.com/blogs/mt/create-immutable-servers-using-ec2-image-builder-aws-codepipeline/. My answer is A, C, F because AMIs should be same (immutable) across environments and use Image Builder into CloudFormation.

ABF makes more sense.. you need to create AMI for each ENV+Release

Using the same image in different environments only works with some additional customization after deployment. Having to specific images per environment does only work for simple cases in a simple way. Most cases you end up creating an EC2 configure customizations and create an Ami from it. Also you want to have something to fix small issues. You do not want to go for prod and risk a downtime when something goes south. So you always want to have something to quickly workaround an issue. Its always quick response to issues via workaround in combination with thorough work in developement. You do not want to keep workarounds, you just want(and need) to buy developement time to do it thorough. A and C we do thorough work. And now F with Cloudformation we can do some final customizations - only what is necesary . So What you would do is put everything that is common on the AMI.

ABE A. Mirroring the application code to an AWS CodeCommit Git repository provides a centralized location to manage the code and ensure consistency across environments. Building EC2 AMIs from the CodeCommit repository ensures that the same codebase is used for all deployments. B. Producing multiple EC2 AMIs, one for each environment, for each release ensures that each environment has its own dedicated AMI that is customized for its specific requirements. This reduces the likelihood of issues occurring due to differences in environment configurations. E. Replacing the custom scripts and tools with AWS CodeBuild and using EC2 Image Builder for infrastructure deployment provides a consistent and reliable process for building and deploying AMIs. This reduces the likelihood of errors occurring during the deployment process.

ACF ok

B - Not best practice and introduces potential issues. D - Seems overly complex, rather than using native AWS services "CodeCommit" E -- ? On the fence, part 2 update infrastructure deployment to use ec2 image builder seems to be inaccurate.

Agree ACF
