A canary-deployment is a release strategy in which a new version of a system is first rolled out to a small subset of users or infrastructure before being deployed to the full population. Parameters: controlled rollout scope (percentage or number of targets), monitoring period for failure detection, automated rollback triggers on degradation thresholds, and a phased expansion protocol. The strategy persists through tooling that automates subset selection, metric comparison between canary and baseline groups, and decision workflows for promotion or rollback.

Definition
Why it is in scope
A deployment strategy where changes are released to a small subset of users or servers before full rollout, allowing failure detection with minimal blast radius. Human-made: an engineered practice codified in CI/CD tooling and operational procedures to reduce the risk of software releases.

Canary deployments are designed and maintained for the sake of reliability: they detect faults before full rollout, limiting exposure and preserving system availability. Law 8d: servant (canary-deployment) → master (reliability). The removal test confirms — remove canary deployments and reliability engineering loses a key prevention mechanism.
- cmsj7rxv402bcnobpg6jkh9slDEPENDS_ON →
Canary deployment needs monitoring to operate: the technique deploys a small subset of new code, then monitors its behavior for errors before a full rollout. Remove monitoring and canary deployment cannot function — you cannot detect whether the canary succeeds or fails without observing it.
