The significance of continuous integration and continuous delivery (CI/CD) in software development lies in their ability to streamline and automate the software release process. CI involves regularly integrating code changes into a shared repository, allowing for early detection of errors and facilitating collaborative development. Continuous delivery ensures that code changes are automatically prepared for deployment to production, which accelerates time-to-market and enhances product quality. Together, CI/CD practices promote rapid iteration, improve collaboration among teams, and increase overall efficiency in delivering software solutions.
