Amazon Elastic Container Service (ECS) is a performant and scalable container management and orchestration service available in the public AWS cloud. It supports running your containers in AWS Fargate or using customizable Amazon EC2 instances. Amazon ECS is also able to integrate seamlessly with other AWS services.

Among the many deployment models you can use with Amazon ECS, blue/green deployments, which allow gated deployments with no downtime, are supported.

In this lab, you will use the AWS Management Console to build Docker images and deploy them using Amazon Elastic Container Service (ECS).
