Reliable cloud messaging as a service (MaaS) and
simple hybrid integration

Distribute messages to multiple independent

Brokering messaging between client and server
with asynchronous operations along with structured first-in, first-out (FIFO)
messaging and publish/subscribe capabilities.

Safely routing and transferring data and control
across service and application boundaries

While a queue is often used for point-to-point
communication, topics are useful in publish/subscribe scenarios.
·      Dead-lettering
- Service Bus supports a dead-letter queue (DLQ) to hold messages that
cannot be delivered to any receiver, or messages that cannot be processed. You
can then remove messages from the DLQ and inspect them.
