CI/CD (Continuous Integration/Continuous Delivery) is a set of practices that automate the integration and delivery of code changes, allowing teams to release software quickly and efficiently.
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.
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).
