"The first official command-line tool for Amazon Elastic Container Service (Amazon ECS) was created in 2015. In December 2019, we shared the preview release of a new command-line experience, redesigned from the ground up to make it easier for you to deploy your applications on Amazon ECS. Today, we are sharing some of our progress on this command-line tool, as well as its new official name: AWS Copilot.AWS Copilot is designed for both existing ECS users, and new ECS users who want to move beyond manual management of lower-level infrastructure, and instead, just start thinking about their application and its lifecycle. Copilot creates modern application deployments by default, based on production-ready patterns that include best practices designed by ECS engineers and customers over the years.If you are designing a new application, you probably start with a whiteboard or mental diagram that has boxes for each service and lines for how they will talk to each other. But later when it’s time to create this architecture, there are a lot more cloud components to think about: VPC subnets, load balancers, deployment pipelines, and durable storage for your application’s stateful data. Copilot handles all these underlying details for you. You just provide your container and then let Copilot handle high availability deployments and load balancer creation and configuration. You can even have Copilot create a deployment pipeline that will automatically redeploy the latest version of your application every time you push a new commit to your code repository.
To summarize, if you use Copilot, you can go from idea to implementation much faster, with the confidence that the infrastructure you have deployed has a production-ready configuration."
