CI/CD (Continuous Integration / Continuous Deployment)

Automatically testing and deploying code changes as they're made, instead of manually bundling and releasing them on an irregular schedule.

Continuous Integration automatically runs tests against every code change to catch problems immediately rather than weeks later. Continuous Deployment automatically ships changes that pass those tests, often multiple times a day, instead of large, risky, infrequent releases. Together they're what makes frequent, low-risk software updates possible rather than a rare, high-stakes event.
