# Canary deploy

> A new version is rolled out to a small slice of traffic (1%, 5%, 25%) before going to 100%.

SLIs (error rate, latency, business metrics) are watched; on regression, automatic rollback. Different from blue-green where two environments swap at once · canary is gradual. Without proper telemetry it is not a canary, just a 'slightly slower deploy'. Tools: Argo Rollouts, Flagger, LaunchDarkly progressive delivery.
