This document compares the CI/CD tools Concourse and Jenkins. It introduces Concourse concepts like tasks, resources, and jobs that make up pipelines. The document discusses key differences between the two tools like Jenkins using plugins while Concourse has no plugins, Jenkins configuring through a UI while Concourse is configured by code, and Jenkins using snowflake build slaves versus Concourse using disposable workers. The document questions if the field is still on the right path with CI/CD tooling and compares solutions between Concourse and Jenkins.
