Canary Release
Canary releases reduce blast radius by exposing a change gradually and monitoring signals.
They are most effective with clear rollback triggers and fast rollback execution.

What is a canary release?
A progressive rollout that exposes a change to a small portion of traffic and monitors signals before expanding.
What signals should we monitor?
Error rate, latency, saturation, user-impact metrics, and domain-specific outcomes.
How do we define rollback triggers?
Use thresholds tied to SLOs and clear, pre-agreed decision rules.
What’s a common failure mode?
Running canaries without clear signals, thresholds, or ownership for rollback decisions.
What’s the first improvement?
Pick 2–3 key signals and define explicit rollback thresholds.
