Plain language
Rolling out new software to a tiny slice of users first, to catch problems before everyone gets it.
As stated in the literature
A deployment strategy that routes a small fraction of traffic to a new version (a 'canary') before full rollout; appears in this corpus as a multi-agent collision scenario and as a target task in GPU/system optimization.
Also called: canary deployment, canary
Why it matters: It catches serious bugs while they affect only a few people, preventing a bad update from breaking the experience for the entire user base.
For example, a company might send a new app update to just 1% of users first, watch for crashes, and only roll it out to everyone once it looks safe.
