AWS CodePipeline vs Concourse

AWS CodePipeline is a fully managed continuous delivery service that automates release pipelines for application and infrastructure updates. It orchestrates build, test, and deploy phases using configurable stages and actions.

Concourse is an open-source CI/CD platform that models continuous integration as simple, reusable, isolated tasks to build modular and composable pipelines. It provides a declarative approach to pipeline management with strong isolation guarantees.
