What is CI/CD (Continuous Integration / Continuous Delivery)?
Turkish: CI/CD
CI/CD makes software releases repeatable by moving code changes through automated build, test, and deployment pipelines.
What is CI/CD?
CI/CD is the practice of automatically building, testing, and delivering software changes without relying on manual release steps. CI means continuous integration; CD can mean continuous delivery or continuous deployment.
In continuous integration, every change pushed by a developer is merged into the shared codebase and checked automatically. In continuous delivery, the pipeline produces a release-ready artifact. In continuous deployment, that artifact is published automatically when the defined checks pass.
Typical Pipeline Stages
- Checking out code from the Git repository
- Installing dependencies
- Running lint, unit tests, and integration tests
- Building the application or Docker image
- Running security and secret scans
- Deploying to staging or production
- Rolling back or redeploying when something fails
Business Use
CI/CD is especially valuable for web applications, SaaS products, mobile backends, and API services that change frequently. The goal is not just faster deployment; it is knowing which commit passed which checks, what version reached which environment, and how to recover when a release fails.
GitHub Actions, GitLab CI, CircleCI, and Jenkins are common tools for these workflows. CI/CD is the technical side of a broader DevOps practice; branch strategy, team agreements, and monitoring are just as important as the pipeline file.
At Barlas Dijital, CI/CD work is usually designed together with automation and maintenance processes.
