I implemented at 4over continuous integration during the year 2019 with David Reynolds. A Developer Manifesto was also produced to guide developers and QA team while producing and testing the codebase.
Continuous deployment advances continuous delivery further at which codes are integrated, deployed to production, automatically tested, and reverted when errors happen. To be specific, every change that passes all production pipelines is deployed directly to production without additional intervention. Therefore, the software release process is faster and more robust through rigorous automated testing without explicit approval from developers.
