On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
pick a way to shift traffic that limits risk.
Planned topics
- Canary: a small share of traffic to the new path, widened as checks pass.
- Blue-green: switch between two full environments; fast rollback, higher cost.
- By tenant, region, or cohort: move one group at a time to learn safely.
- Match strategy to risk: reads before writes, internal users before customers.
- Define go and stop criteria before the rollout starts.
Draft outline details
Demonstration
Strategy table: strategy | when to use | rollback speed | cost. Add a rollout plan: 1% internal, 5% customers in one region, 25%, 100%, with a bake time per step.
