Cloud Architect Interview Scenarios

Scenario — Multi-AZ production service

Design a customer-facing system that must survive a single availability-zone failure.

Cover:

• Stateless compute and load balancing.
• Data durability and failover.
• Health checks and recovery.
• RTO/RPO.
• Observability.
• Cost implications.

Scenario — Growing workload

Traffic is growing rapidly and the system is approaching its limits.

Start with requirements and bottleneck evidence, then explain which layer you would scale, how you would verify capacity, and what trade-off you accept.
