DevOps Dictionary

Continuous Integration is a software development practice where engineers merge small, frequent changes into a shared main branch and rely on automation to verify each change. A CI system runs a repeatable pipeline on every commit or pull request, typically compiling the code and executing automated tests and basic quality checks, so integration problems are detected close to when they are introduced. It addresses the classic issue of “integration pain,” where teams work on long-lived branches and only discover conflicts, broken builds, or regressions late in the cycle.

With Continuous Integration, teams get fast feedback, keep the main branch in a releasable state, and reduce surprises during release; without it, defects and merge conflicts accumulate, failures surface late, and delivery becomes slower and riskier. This gap exists because frequent merges plus automated validation shorten the time between a change and its impact, making integration a routine, low-drama activity.
