Continuous Integration/Continuous Deployment (CI/CD) is a software development practice that automates the process of integrating code changes and deploying applications. In CI, developers frequently merge their code changes into a shared repository, where automated tests run to ensure the new code works correctly. This helps identify issues early in the development cycle. In CD, the process extends to automatically deploying the validated code to production environments. This allows teams to deliver updates and new features to users quickly and reliably. CI/CD practices enhance collaboration, reduce manual errors, and improve overall software quality.
