CI/CD is an acronym that stands for Continuous Integration and Continuous Deployment/Delivery. It is a set of practices used in software development to automate the process of building, testing, and deploying software changes.
Continuous Integration (CI) is the practice of frequently merging code changes from multiple developers into a shared repository, and automatically building and testing the code to catch any issues early in the development process. This helps to ensure that the software is always in a releasable state.
Continuous Deployment/Delivery (CD) is the practice of automating the process of deploying the software changes to a production environment. With CD, the changes that pass the automated testing and quality checks are automatically deployed to production without manual intervention.
Together, CI/CD aims to automate the software development process and provide rapid feedback to developers, allowing them to iterate quickly and release new features more frequently with higher quality and fewer errors. It also helps to reduce the time and effort required to deploy software changes to production, increasing the efficiency and reliability of the software development process.
