AWS Certified Cloud Practitioner — Question 350

A company wants to deploy and manage a Docker based application on AWS.

Which solution meets these requirements with the LEAST amount of operational overhead?

Answer options

• A. An open source Docker orchestrator on Amazon EC2 instances
• B. AWS AppSync
• C. Amazon Elastic Container Registry (Amazon ECR)
• D. Amazon Elastic Container Service (Amazon ECS)

Correct answer: D

Explanation

Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service that allows you to easily run and scale Docker containers on AWS with minimal operational overhead. Running an open-source orchestrator on EC2 instances introduces significant management complexity, while Amazon ECR is only a container registry for storing images rather than running them. AWS AppSync is a managed GraphQL service and is not designed for hosting Docker-based applications.
