By use case
Canary Releases
Expose new behavior to a small cohort first, monitor live health signals, and expand only when confidence rises.
When to use this playbook
- You are launching risky logic and need production validation before full release.
- Cross-service dependencies make lower-environment validation incomplete.
- You need a repeatable rollout shape that can be paused at each stage.
Canary sequence
- 1. Start with an internal cohort. Validate basic behavior and observability instrumentation first.
- 2. Expand to low-risk traffic. Increase exposure to a narrow percentage or low-impact segment.
- 3. Compare guardrails against baseline. Monitor errors, latency, and business KPI deltas at each checkpoint.
- 4. Promote gradually or rollback instantly. Move to broad rollout only after checkpoint criteria are met.
