How would you answer an interview scenario involving load balancing and traffic management in Cloud Architecture?
For an interview scenario involving load balancing and traffic management, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Traffic-management services distribute requests across healthy endpoints and can route by geography, latency, path, hostname, or health. In this scenario, a deployment makes half the instances unhealthy. Explain how traffic management should detect and isolate them. For production, design layered health checks, remove unhealthy instances quickly, preserve session strategy deliberately, and test failover. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
