What does "canary deployment" mean in programming?
canary deployment is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A deployment strategy where a new version is rolled out to a small percentage of users first. If the canary shows no errors, the rollout gradually increases to 100%. If it fails, only a small number of users are affected and the rollback is fast.
Example
"We did a canary deploy to 5% of traffic. Metrics look good, so we are rolling out to everyone."
