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