CI/CD (Continuous Integration / Continuous Deployment) is automated software delivery practices that test and deploy code changes continuously.
CI/CD pipelines (GitHub Actions, GitLab CI, CircleCI, Jenkins) automatically test code on every commit and deploy passing changes. By 2026, deploy frequency is a key DORA metric — elite teams deploy 100+ times per day. Required for safe, fast iteration. Modern stacks integrate security scanning (Snyk, GitGuardian) and feature flags into pipelines.
CI/CD turns deploys from a risky, manual event into a routine, automated one. The biggest gain is not speed — it is reliability and the team's confidence to ship small, frequent changes.
Every pull request triggers an automated pipeline: tests run, the build is created, security scans execute, and on merge to main the change deploys to production within minutes — without anyone manually clicking deploy.
CI/CD does not mean "deploy as fast as possible." It means deploys are automated and consistent; the right pace depends on the product, regulation and risk tolerance.
Optimize pipeline speed; engineers will work around slow CI by batching changes, which negates most of the CI benefit and increases blast radius per deploy.
