What is CI/CD?
In software engineering term, CI/CD (CICD, or CI-CD) is referred to combined exercise of continuous integration and continuous deployment or development.
CI/CD bridges the gaps between development and operation teams and their activities by enforcing automation in the building, testing, and deployment of application program. Unlike traditional methods where all updates are integrated into one large batch before rolling out the newer version, CI/CD doesn’t do that.
Modern-day approach is continuous development, continuous testing, continuous integration, continuous deployment, and continuous monitoring of application software throughout its development lifecycle.
CI/CD forms the backbone of modern-day DevOps operations.
Take an example of Ubuntu versions, a clean real life instance of CI/CD practice.
