CI/CD Pipelines

Continuous Integration (CI) means every commit is built and tested. Continuous Deployment (CD) means every tested commit can be deployed. CI/CD pipelines automate these steps: code push → build → test → scan → deploy. Pipelines catch bugs early (before code review), prevent bad code reaching production (failed tests block merge), and enable rapid feedback (minutes, not days).

This section covers:

• Build, Test, Scan: What happens before merge
• Promotion and Approvals: Gates and controls for safety
• Deployment Strategies: Blue-green, rolling, canary—how to roll out changes

📄️ Build, Test, and Scan

Automate compilation, testing, and security scanning to catch issues before production.

📄️ Promotion, Approvals, and Gates

Control flow of changes through environments; approve releases with appropriate rigor.

📄️ Blue-Green, Rolling, and Canary Deployments

Roll out changes safely with zero-downtime deployment strategies; detect problems before all users are affected.
