In 30 seconds
- Passing changes deploy to production automatically.

- The shortest possible path from commit to customer.
How it works
It's continuous delivery with the last manual step removed. If every automated check passes, the change goes live. Teams practising it often deploy many times a day.
Before you try it
- Trustworthy automated tests
- Production monitoring and alerting
- Fast, automated rollback
- Feature flags to hide unfinished work
Making it safe
Keep each change small, roll out gradually to a fraction of users, and watch key signals. A failure in a tiny change is easy to find and fix. See delivery vs deployment.
