Azure Service Bus Queues vs Topics for one to many(unique)

Question

I have a service on azure that send data to on-premise clients asynchronously. The filter for the unique code on the message os different for everyone which is why the message is not broadcasted. I am using a single topic for it for now, but a different approach using queues may be better.

Answer 1

The topic and subscription service provided by Azure can help you with this requirement. Here is why it is so:

1.  The queues might increase the complexity as you will have to specify and ensure that the queue is prepared before it starts sending out the messages. Whereas, the routing logic is currently being run by azure bus service which is based on the rules configured by you. 
2. The true SQL rule will be coming up in Topics and Subscriptions in azure which will help you to build an audit trail.
