Intermediate Topic 21 of 50 DevOps & Tooling

Continuous Delivery

Keeping software always releasable via automated pipelines.

How it works

Continuous delivery extends continuous integration so every change that passes the pipeline is automatically packaged and ready to release at any time. The pipeline builds an artifact once, deploys it through environments such as staging, runs integration, performance and smoke tests, and then waits for approval or releases automatically, which is called continuous deployment. Automation covers database migrations, configuration and rollbacks. Releases become small, frequent and low risk because deployment is separated from the decision to expose a feature to users.

Where it is used

Teams use it to ship many times a day, shorten feedback loops and avoid stressful big-bang release weekends, with metrics such as lead time and change failure rate guiding improvements.

Common pitfall

Manual steps and environments that differ from production undermine confidence, and rebuilding per environment can deploy untested bits. Promote the same artifact through every stage, automate rollbacks and make database changes backward compatible.

Where it fits in the course
