Queue Storage for large simple backlogs
Copperfield Print queues work items for background processing. Messages are small, ordering and transactions are not needed, and during seasonal peaks the backlog in a single queue can exceed 80 GB. The team wants the simplest and cheapest messaging service. What should you recommend?
- A.An Event Grid topic with a webhook subscriber
- B.Service Bus queues in the Standard tier
- C.Azure Queue Storage
- D.An event hub that retains events for seven days
Show answer and explanation
Correct answer: C. Azure Queue Storage
Why: Queue Storage offers simple, low-cost queues whose total size is limited only by the storage account's capacity, which suits very large backlogs when advanced broker features are not needed. Service Bus queues have a maximum entity size of tens of gigabytes and add features this workload does not use. Event Grid delivers events rather than holding a work backlog, and Event Hubs is built for telemetry streams.
