Why CI / CD is important for software projects

CI/CD stands for continuous integration and continuous deployment, practices that help development teams merge code frequently and deploy changes to production automatically. Continuous integration involves merging code changes multiple times per day to avoid conflicts from long-lived feature branches. Continuous deployment automatically pushes merged changes to production, often multiple times daily. Implementing CI/CD requires extensive automated testing (unit, integration, end-to-end), infrastructure as code tools like Terraform, and deployment automation through pipelines using tools like GitHub Actions or CircleCI. While challenging to implement perfectly, especially for large teams, CI/CD reduces deployment risks and enables faster bug fixes and feature delivery.
