Extreme DevOps Basics arena: traffic switching, health verification, rollback triggers, and migration safety
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: devops-easy-blue-green-cutover
A release needs zero downtime while a schema-compatible migration rolls out. You are working inside a deployment operations lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply traffic switching, health verification, rollback triggers, and migration safety in a deployment operations lab while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates traffic switching, health verification, rollback triggers, and migration safety
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
