CI/CD

Insoftware engineering, CI/CDorCICD is the combined practices of continuous integration (CI) and continuous delivery (CD) or, less often, continuous deployment.^[1] They are sometimes referred to collectively as continuous development or continuous software development.^[2]

Comparison[edit]

Continuous integration

Frequent merging of several small changes into a main branch.

Continuous delivery

When teams produce software in short cycles with high speed and frequency so that reliable software can be released at any time, and with a simple and repeatable deployment process when deciding to deploy.

Continuous deployment

When new software functionality is rolled out completely automatically.

Motivation[edit]

CI/CD bridges the gaps between development and operation activities and teams by enforcing automation in building, testing and deployment of applications. CI/CD services compile the incremental code changes made by developers, then link and package them into software deliverables.^[3] Automated tests verify the software functionality, and automated deployment services deliver them to end users.^[4] The aim is to increase early defect discovery, increase productivity, and provide faster release cycles. The process contrasts with traditional methods where a collection of software updates were integrated into one large batch before deploying the newer version. Modern-day DevOps practices involve:

• continuous development,
• continuous testing,
• continuous integration,
• continuous deployment, and
• continuous monitoring

of software applications throughout its development life cycle. The CI/CD practice, or CI/CD pipeline, forms the backbone of modern day DevOps operations.
