AWS continuous integration and deployment service that automates your software release process. Like a factory assembly line for code that automatically tests and deploys changes.
When developers push code changes, CodePipeline automatically runs tests and deploys successful builds to production.
All are managed CI/CD services that automate build, test, and deployment workflows. AWS CodePipeline primarily orchestrates stages and integrates with build/deploy tools (e.g., CodeBuild, CodeDeploy), while Azure Pipelines includes built-in CI/CD with broad language support, Google Cloud Build focuses on containerized build steps and triggers, and OCI DevOps provides separate build and deployment pipelines with artifact and environment management.
