Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 27 discussion

D is undoubtedly is most correct one . But they shoud mention that , we are going to deploy application in different environment . Since deployming to the same envirnmont just overide the previous deployment . In order to meed the requirement of Blue / Green deployment we need two separate enviormnent . Then we have two separate version running simulateously and we can do DNS swapping to quicky shilf traffic .

AWS Elastic Beanstalk deploy action can be used to deploy the application artifact from the S3 bucket to the green environment, which is the AWS cloud environment here.

Lightsail does not have built-in Blue/Green deployment capabilities like Elastic Beanstalk.

I was about to discard D because I was unsure if beanstalk supported GO (yes it does ) https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/concepts.platforms.html So D is undoubtedly the best option to quickly move to cloud and to do blue green with an testing

I guess D is easiest option to orchestrate blue/green deployments and A/B testing in this case.

D elastic beanstalk due to deployment options

Maybe D, but it looks like an old approach. we need to use codebuild and codepipelines and Elastic beanstalk, but elastic beanstalk could be changed by AWS cloudformation.

D. Use AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3. Use that location to deploy new versions of the application. Use Elastic Beanstalk to manage the deployment options. AWS Elastic Beanstalk provides a platform for deploying web applications, which is well-suited for use cases that require blue/green deployments and A/B testing. Elastic Beanstalk can deploy applications written in a variety of programming languages and frameworks, including Go. Elastic Beanstalk supports blue/green deployments, which allow you to deploy a new version of your application to a separate environment before switching traffic to it. This enables you to perform A/B testing before fully rolling out a new version of your application. Elastic Beanstalk also allows you to manage the deployment options, including the deployment strategy, instance types, and autoscaling options.

D it is
