You are working for a company that has an on-premises infrastructure. There is now a decision to move to AWS. The plan is to move the development environment first. There are a lot of Docker-based applications that need to be migrated. You want to migrate the applications using the easiest way and least code change. In the meantime, you need an AWS service that can run, stop and manage containers on a cluster. Which of the following is the most appropriate?

Answer options:

A.Deploy the docker containers through AWS ECS service.
B.Use OpsWorks to deploy the docker containers.
C.Use Elastic Beanstalk to deploy the docker containers.
D.Use CloudFormation to deploy the docker containers.

Answer - A
Option A is CORRECT because ECS is a highly scalable, fast container management service that manages the Docker containers on a cluster. It can achieve all the requirements.
Options B, C and D are incorrect because all of these services are not Docker specific and do not operate Docker containers through a cluster.
