Canary Deployment
A rollout practice that exposes a new software version to a small subset of users instances or traffic before expanding it.
Plain English
Release to a limited group first and watch the results before sending the version everywhere.
In context
A canary deployment limits initial exposure while teams compare health and product signals then continue pause or roll back based on defined evidence.
Example
“Send five percent of production traffic to the canary deployment and monitor payment errors.”

Common misunderstanding
A canary deployment reduces initial blast radius but does not make a release safe without representative traffic observability and rollback readiness.
