What is Concourse?
Concourse's principles reduce the risk of switching to and from Concourse, by encouraging practices that decouple your project from your CI's little details, and keeping all configuration in declarative files that can be checked into version control.
Concourse is a tool in the Continuous Integration category of a tech stack.
