Migrating Docker-based Applications to AWS

Prev Question Next Question

Question

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?

A. B. C. D.

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.

The most appropriate service to use for deploying Docker containers on AWS with the easiest way and least code change is AWS Elastic Container Service (ECS) (option A).

AWS ECS is a fully managed container orchestration service that allows you to easily run and scale Docker containers on a cluster of Amazon EC2 instances. With ECS, you can quickly deploy your Docker-based applications without having to worry about infrastructure management, including the configuration of the underlying Amazon EC2 instances.

Using AWS ECS to deploy Docker containers offers several benefits:

  • Fully managed service: AWS ECS is a fully managed service, which means that AWS takes care of the underlying infrastructure, including provisioning and scaling of the EC2 instances, so you don't have to.
  • Integration with AWS services: AWS ECS integrates with other AWS services, such as Amazon S3, Amazon CloudWatch, and AWS Identity and Access Management (IAM), allowing you to easily create and manage your containerized applications.
  • Ease of deployment: With AWS ECS, you can deploy your Docker containers quickly and easily, with minimal code changes.
  • Autoscaling: AWS ECS can automatically scale your containerized applications based on demand, ensuring that your applications are always available to users.

On the other hand, the other options listed are not the most appropriate in this scenario:

  • Option B (OpsWorks) is a configuration management service that can be used to automate the deployment of applications on Amazon EC2 instances, but it is not specifically designed for containerized applications.
  • Option C (Elastic Beanstalk) is a platform as a service (PaaS) that can be used to deploy web applications, but it is not specifically designed for containerized applications either.
  • Option D (CloudFormation) is an infrastructure as code (IaC) service that can be used to deploy and manage AWS resources, but it is not specifically designed for containerized applications either.
