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?

Chose D1
D attends MINIMAL disruptions since there are two target groups in parallel, besides attend MINIMAL changes, since API is not changed.
Chose A1
Keywords: minimal disruptions, MINIMAL changes
Chose A2
I chose A because the question says MINIMAL changes to the application. Canary deployment needs minimal changes to the application as it requires only adding canary settings to the deployment stage. AWS API Gateway supports canary deployments, allowing you to route a percentage of your traffic to a new stage or version of your API.
