CI/CD stands for Continuous Integration and Continuous Deployment, a set of practices that automate the process of testing, integrating, and releasing software updates. With CI, developers regularly merge code changes into a shared repository, where automated tests check for errors and compatibility. CD then automates the delivery and deployment of these changes to production environments, ensuring new features, bug fixes, or updates reach users quickly and reliably. CI/CD reduces manual work, speeds up development cycles, and improves software quality by catching issues early and making releases more predictable.
