What is CI/CD? - Definition & Meaning
CI/CD stands for Continuous Integration and Continuous Delivery/Deployment. Learn how CI/CD pipelines accelerate software development and improve quality.
Definition
CI/CD (Continuous Integration / Continuous Delivery) is a set of practices where code changes are automatically built, tested, and prepared for deployment. Continuous Integration focuses on frequently merging code, while Continuous Delivery enables automated rollout to production.
Technical Explanation
A CI/CD pipeline typically consists of stages: source (code-commit trigger), build (compilation and dependency resolution), test (unit, integration, and end-to-end tests), and deploy (staging/production). Tools like GitHub Actions, GitLab CI, Jenkins, and CircleCI orchestrate these steps. Artifacts are stored in container registries or package repositories. Feature flags and canary deployments reduce release risk. The pipeline is defined as code (YAML or DSL) and version-controlled alongside the application code.
How Refront Uses This
Refront runs on automated CI/CD pipelines that automatically execute tests and deploy the application on every code push. This ensures customers always use the latest version without manual intervention. The Cursor MCP integration triggers CI/CD runs when an AI agent proposes code changes.
Examples
- •On every pull request, the CI pipeline automatically runs 500+ tests to prevent regressions.
- •After a code review is approved, the change is automatically deployed to the staging environment via the CD pipeline.
- •A team uses feature flags combined with CI/CD to gradually roll out new features to users.
Frequently Asked Questions
What is the difference between Continuous Delivery and Continuous Deployment?
Continuous Delivery means code is always ready for deployment but requires manual approval. Continuous Deployment goes one step further and automatically deploys to production as soon as all tests pass, without human intervention.
Which tools are most commonly used for CI/CD?
GitHub Actions, GitLab CI/CD, Jenkins, CircleCI, and Azure DevOps Pipelines are the most popular CI/CD tools. The choice depends on the team's version control system and hosting environment.
How long does it take to set up CI/CD?
A basic CI/CD pipeline can be set up in a few hours with managed tools like GitHub Actions. More complex setups with multiple environments, integration tests, and canary deployments require more time and expertise.
