The function of a Continuous Integration/Continuous Deployment (CI/CD) pipeline is to automate the process of integrating code changes, testing, and deploying applications to production environments. CI/CD pipelines enable developers to commit code frequently, which triggers a series of automated tests and builds to validate changes and ensure code quality. Successful builds can be deployed to production with minimal manual intervention, enhancing deployment speed and frequency. This approach not only increases operational efficiency but also reduces the risk of introducing bugs into live systems. Ultimately, CI/CD pipelines support agile development practices, enabling teams to respond quickly to customer feedback and evolving requirements.
