A company wants to migrate its existing on-premises monolithic application to AWS.The company wants to keep as much of the front-end code and the backend code as possible.However, the company wants to break the application into smaller applications.A different team will manage each application.The company needs a highly scalable solution that minimizes operational overhead.

Which solution will meet these requirements?

Host the application on AWS Lambda. Integrate the application with Amazon API Gateway.

Host the application with AWS Amplify. Connect the application to an Amazon API Gateway API that is integrated with AWS Lambda.

Host the application on Amazon EC2 instances. Set up an Application Load Balancer with EC2 instances in an Auto Scaling group as targets.

Host the application on Amazon Elastic Container Service (Amazon ECS). Set up an Application Load Balancer with Amazon ECS as the target.

Explanations:

AWS Lambda is a serverless solution ideal for stateless, event-driven workloads. It would not be a good fit for hosting a monolithic application, which likely requires more control over the environment. While Lambda integrates well with API Gateway, it is not the best solution for breaking down a monolithic application into smaller applications.

AWS Amplify is designed primarily for front-end and mobile app development, not for backend-heavy monolithic applications. Integrating with API Gateway and Lambda adds complexity without providing a clear path for breaking up a monolithic app. It is more suited for hosting full-stack web apps but not ideal for a backend monolith.

Hosting on Amazon EC2 instances involves managing the infrastructure, which increases operational overhead. While EC2 can scale using Auto Scaling and Application Load Balancer, this option does not meet the goal of minimizing operational overhead or breaking the monolith into smaller applications.

Amazon ECS is a fully managed container orchestration service that allows you to run and scale containerized applications. It fits well with microservices architectures, making it ideal for breaking up a monolithic application into smaller, manageable services. ECS minimizes operational overhead compared to EC2 instances and integrates easily with Application Load Balancer for scalability.

    I value that the answer is:
    Host the application on Amazon Elastic Container Service (Amazon ECS). Set up an Application Load Balancer with Amazon ECS as the target.
