The AWS Copilot CLI is a tool for developers to build, release, and operate production ready containerized applications on Amazon ECS and AWS Fargate. Copilot takes best practices, from infrastructure to continuous delivery, and makes them available to customers from the comfort of their command line. Whether you are setting up a single-service application or several micro-services application, Copilot enables you to use service patterns like a load balanced web service to provision infrastructure, deploy to multiple environments like testing or production, and even use an AWS CodePipeline release pipeline for automated deployments. You can also monitor the health of your service by viewing your service's status or logs, scale up or down production services, and spin up a new environment for automated testing. To add additional resources and operate the environment outside the CLI, customers can export the environment to AWS CloudFormation.
