Last Updated: December 30, 2025
What is a CI/CD Pipeline?
A CI/CD (Continuous Integration/Continuous Deployment) Pipeline is an automated workflow that builds, tests, and deploys code changes from development to production.
The core idea is to automate the software delivery process so that developers can push code frequently while maintaining quality and reliability. Every code commit triggers a series of automated steps: building the application, running tests, creating artifacts, and deploying to various environments.
Popular Examples: Jenkins, GitHub Actions, GitLab CI/CD, CircleCI, Azure DevOps
This system design problem touches on distributed systems, job scheduling, artifact management, and deployment strategies, concepts that are fundamental to modern software engineering.
In this chapter, we will explore the high-level design of a CI/CD Pipeline.
Lets start by clarifying the requirements:
