CI/CD

CI/CD is like an assembly line in a factory where each piece is added and tested continuously until the final product is complete.

A development team uses CI/CD to automatically test and deploy code changes to production multiple times a day.

CI/CD ensures that code changes are tested and delivered quickly, reducing the time to market and increasing software quality.

CI/CD can lead to faster release cycles, fewer bugs in production, and improved collaboration among development teams.

• Use Case 1: In fast-paced development environments where quick, frequent releases are necessary.
• Use Case 2: When maintaining complex systems where automated testing and integration reduce the risk of introducing bugs.
• Use Case 3: For large teams working on the same codebase, ensuring that changes integrate smoothly and don’t break the build.

Automate as much of the process as possible; ensure thorough testing at each stage; keep the pipeline fast and reliable.

Inadequate test coverage leading to undetected bugs; complex pipelines that are difficult to maintain; failing to keep CI/CD tools updated.

Deployment frequency, lead time for changes, change failure rate, mean time to recovery (MTTR).
