What is CI/CD?
Continuous Integration and Continuous Delivery: the practice of frequently merging code changes into a shared repository (CI) and automatically preparing them for release (CD). The goal is to make deployment boring, routine, and low-risk.
My perspective
In practice
The infrastructure that makes all other XP practices sustainable. Without CI/CD, TDD and refactoring lose their safety net. With it, teams can deploy confidently, multiple times a day if needed.
