Topic 1 Question 455
A company needs to migrate 60 on-premises legacy applications to AWS. The applications are based on the NET Framework and run on Windows.

The company needs a solution that minimizes migration time and requires no application code changes. The company also does not want to manage the infrastructure.

Which solution will meet these requirements?
- Refactor the applications and containerize them by using AWS Toolkit for NET Refactoring. Use Amazon Elastic Container Service (Amazon ECS) with the Fargate launch type to host the containerized applications.
- Use the Windows Web Application Migration Assistant to migrate the applications to AWS Elastic Beanstalk. Use Elastic Beanstalk to deploy and manage the applications.
- Use the Windows Web Application Migration Assistant to migrate the applications to Amazon EC2 instances. Use the EC2 instances to deploy and manage the applications.
- Refactor the applications and containerize them by using AWS Toolkit for NET Refactoring. Use Amazon Elastic Kubernetes Service (Amazon EKS) with the Fargate launch type to host the containerized applications.

- Solution: B If you look at the request "Company needs a solution that minimizes migration time and requires no changes to application code," you can eliminate the answer under A & D (refactoring suggested). The answers under B & C are fine, but the "minimize migration time" part, the better solution is under B.

  Correct answer is B, use Beanstalk. It's a classic use for Beanstalk: remember - no application changes is a requirement.
  
  A involves quite a bit of work and application changes. AWS Toolkit for .NET is a help, but there's operational overhead. Also, moving to ECS Fargate, serverless as it is, requires containerising the application, which also adds overhead.

  I vote for B when googling Windows Web Application Migration Assistant, all top 3 are using EB. https://github.com/awslabs/windows-web-app-migration-assistant Compare to EC2 in C, the question mentioned do not manage infrastructure See below wording With Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without having to learn about the infrastructure that runs those applications https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/Welcome.html
