CI/CD (Continuous Integration/Continuous Delivery) is a software development practice and delivery pipeline that emphasizes automation, collaboration, and rapid iteration. Continuous Integration (CI) involves automating the process of integrating code changes into a shared repository, running automated tests, and detecting integration errors early in the development lifecycle. Continuous Delivery (CD) extends CI by automatically deploying code changes to production environments after passing automated tests, ensuring fast and reliable delivery of software updates to end-users.
