Which best practice of the AWS Well-Architected Framework is the company following with this plan?
Integrate functional testing as part of AWS deployment.
Use automation to deploy changes.
Deploy the application to multiple locations.
Implement loosely coupled dependencies.
Explanations:
Integrating functional testing as part of AWS deployment focuses on ensuring the quality of the code before deployment, which is not directly related to the migration strategy or the microservices architecture.
While using automation to deploy changes is a good practice, it does not specifically address the need to break down a monolithic application into microservices or the associated benefits of that approach.
Deploying the application to multiple locations relates to availability and fault tolerance but does not address the issue of monolithic architecture versus microservices.
Implementing loosely coupled dependencies is a core principle of microservices architecture, allowing services to be developed, deployed, and scaled independently, which addresses the challenges faced by the current monolithic application.
I map out that the answer is:
Implement loosely coupled dependencies.
