A canary deployment is a progressive rollout of an application that splits traffic between an already-deployed version and a new version, rolling it out to a subset of users before rolling out fully.

A canary deployment is a method that exposes a new feature to an early sub-segment of users. The goal is to test new functionality on a subset of customers before releasing it to the entire user base.

You can choose randomly or a specific group of users and roll back if anything breaks. If everything works as intended, you can gradually add more users while monitoring logs, errors, and software health.
