Topic 1 Question 143
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.

I think the answer here is "D" because usually when you see terms like "monolithic" the answer will likely refer to microservices.

D is organic pattern, lift and shift, decompose to containers, first making most use of existing code, whilst new features can be added over time with lambda+api gw later. A is leapfrog pattern. requiring refactoring all code up front.

The correct answer is Option D. To meet the requirements, the company should host the application on Amazon Elastic Container Service (Amazon ECS) and set up an Application Load Balancer with Amazon ECS as the target.
Option A is not a valid solution because AWS Lambda is not suitable for hosting long-running applications.
Option B is not a valid solution because AWS Amplify is a framework for building, deploying, and managing web applications, not a hosting solution.
Option C is not a valid solution because Amazon EC2 instances are not fully managed container orchestration services. The company will need to manage the EC2 instances, which will increase operational overhead.
