This one's built for teams who need their CI/CD pipelines to actually be secure and fast, not just functional. It covers GitHub Actions, GitLab CI, and Jenkins with a strong TDD approach to pipeline development. You get concrete patterns for dependency caching, parallel execution, and conditional workflows that can shave real minutes off build times. The security focus is legitimate too: OIDC authentication, artifact signing, supply chain hardening, and proper secrets management. What I like is it treats pipelines as high-risk infrastructure instead of glorified bash scripts. If you're debugging why your Actions workflow takes twelve minutes or need to add SAST gates without breaking everything, this has the patterns you need.
