CI/CD Concepts

Continuous Integration validates changes automatically; Continuous Delivery/Deployment releases them safely and frequently.

Pipeline stages

• Build: compile, package, create artifacts
• Test: unit, integration, end-to-end
• Security: scan dependencies, SAST, container scans
• Deploy: staging → production with approvals/rollbacks
