What Is a Canary Deployment?
Canary deployment is a technique used to reduce the risk of introducing a new software version in production by slowly rolling out the change to a small subset of users before rolling it out to the entire infrastructure. This can help to ensure that the new version does not have any unexpected problems or bugs that could impact the stability of the system.
In a canary deployment, the new version of the software is first deployed to a small group of users, often referred to as a “canary group.” The performance of the new version is then monitored closely to ensure that it is functioning as expected. If any issues are detected, the rollout can be stopped before it affects the entire user base. If the canary group does not experience any problems, the new version can be rolled out to the rest of the users.
Canary deployments can provide additional control and flexibility when rolling out new software versions, especially in conjunction with other techniques such as feature flags and blue-green deployments.
