CICDpipelines

CICD pipelines are automated sequences that build, test, and deploy software in a repeatable and reliable manner. They are designed to convert frequent code changes into trusted releases by automating repetitive tasks and providing rapid feedback to developers. A typical pipeline begins with source control and ends with deployment to one or more environments.

Core stages commonly include continuous integration, where changes pushed to a shared repository trigger automated builds and tests; continuous delivery, which ensures the codebase can be released to production with a manual approval step; and continuous deployment, which automatically releases changes to production after passing tests. Pipelines orchestrate builds, unit and integration tests, packaging of artifacts, and provisioning of environments through automation.

Pipelines are often treated as code, defined in configuration files and stored with the application's source. Infrastructure as code and environment templates enable consistent environments; feature flags and canary releases support controlled rollouts; automated rollback mechanisms protect against failed deployments. Quality gates such as static analysis, dependency checks, and security scanning are commonly integrated early in the pipeline.

Key metrics include cycle time, lead time, change failure rate, and mean time to recovery. Adoption emphasizes shifting testing and compliance left, providing transparent pipeline visibility, and delivering rapid feedback to development teams. Common challenges include flaky tests, pipeline maintenance, and managing secrets and permissions.

Popular tools vary by ecosystem and include Jenkins, GitLab CI, GitHub Actions, CircleCI, and Azure DevOps. CI/CD pipelines are widely used to improve release velocity and reliability, though they require ongoing governance and maintenance to remain effective.
