How CI/CD works: why releasing code every day is safer than once a month

Some software teams release new code once a month, late at night, and fear it. Others release many times a day, and their changes fail less often. The difference has a name: CI/CD. Follow a small team and its laundry app from a painful release day to calm daily deploys, with continuous integration, a pipeline that checks every change, staging, continuous delivery and continuous deployment, and the safety nets around them. Then see what more than ten years of research found about speed and safety.
