Your company is planning to move an existing portal to AWS. Currently, it’s running in on-premises. It is a 5-year-old portal developed on Java and MySQL 5.6. Your company is looking to dockerize the application and deploy it in a highly available environment in AWS. You also need a serverless compute engine for containers so that you do not need to provision and manage servers. Which of the following methods is the most suitable?

Answer options:

A.Deploy the Application on Amazon ECS with EC2 Launch Type and leverage Amazon RDS MySQL for the database.
B.Deploy the Application on Amazon EC2 and leverage the Amazon Aurora MySQL for the database.
C.Containerize the Java based application, store Container image in Docker Hub and deploy it in ECS with EC2 Launch Type. Leverage Amazon Aurora MySQL for the database.
D.Containerize the Java based application, store Container image in ECR and deploy it in ECS with AWS Fargate Launch Type. Leverage Amazon Aurora MySQL for the database.

Answer: D
Option A is incorrect because the Client is looking to dockerize the App in a serverless environment. Amazon ECS with EC2 Launch Type is not the best case here.
Option B is incorrect because the Client is looking for dockerizing the App in a serverless environment. Amazon EC2 is not the best case here.
Option C is incorrect because ECS with EC2 Launch Type is not a serverless environment.
Option D is CORRECT because ECS with AWS Fargate Launch Type provides a highly available and serverless environment. This option meets the requirements of the question.
