How do you perform a zero-downtime blue-green deployment in Container Apps?
- A Deploy to a new environment
- B Use single revision mode with health checks
- C Use multiple revision mode, route 100% traffic to the new revision after validation (correct answer)
- D Delete old revision before deploying new one
Shortcut: In multiple revision mode, deploy the new revision with 0% traffic. After validation, shift traffic (0% old → 100% new) using traffic weights. Then deactivate the old revision.
