Trap Question — “What if your Service Bus?

Short answer: goes down?” Strong Answer: First, Azure Service Bus is highly available, but still I design for failure. Mitigation: Retry with exponential backoff Use secondary region (Geo-disaster recovery) Persist critical data before publishing Advanced insight: Never rely on a single point of failure.

Real-world example (ShopNest)

Order-paid events go to Service Bus; an Azure Function sends the confirmation email asynchronously.
