What is the key difference between Azure Service Bus queues and Azure Storage queues?

Accepted Answer

Service Bus supports advanced messaging features like dead-lettering, sessions, and transactions

Answer

Service Bus provides enterprise messaging with dead-letter queues, message sessions, duplicate detection, and transactions not available in Storage queues.

Question 2

In Azure Service Bus, what feature ensures that only one consumer processes a related group of messages in order?

Message sessions

Message sessions (enabled per queue/subscription) group related messages by session ID and guarantee ordered, exclusive processing by one consumer at a time.
