Amazon Elastic Container Service (Amazon ECS) is a highly scalable, high-performance container orchestration service that supports Docker containers and allows you to easily run and scale containerized applications on AWS.

Amazon ECS eliminates the need for you to install and operate your own container orchestration software, manage and scale a cluster of virtual machines, or schedule containers on those virtual machines.

Infrastructure Integration Amazon ECS makes it easy to build performant, modern applications on AWS and features AWS Fargate so you can deploy and manage containers without having to provision or manage any servers.  Amazon ECS is deeply integrated with key AWS services including Elastic Load Balancing, Amazon VPC, AWS IAM, Amazon ECR, AWS Batch, Amazon CloudWatch, AWS CloudFormation, AWS CodeBuild, AWS CodePipeline, AWS CloudTrail, and Route 53 AutoNaming for Service Discovery.
