Question

A company recently migrated its legacy application from on-premises to AWS. The application is hosted on Amazon EC2 instances behind an Application Load Balancer, which is behind Amazon API Gateway. The company wants to ensure users experience minimal disruptions during any deployment of a new version of the application. The company also wants to ensure it can quickly roll back updates if there is an issue. Which solution will meet these requirements with MINIMAL changes to the application?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Introduce changes as a separate environment parallel to the existing one. Configure API Gateway to use a canary release deployment to send a small subset of user traffic to the new environment. Amazon API Gateway is a fully managed front door for creating and securing APIs at scale. AWS Config tracks resource configuration changes and evaluates compliance.
