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:
