 Service Bus topics and subscriptions support a *publish/subscribe* messaging communication model. When using topics and subscriptions, components of a distributed application do not communicate directly with
 each other; instead they exchange messages via a topic, which acts as an intermediary.

 In contrast with Service Bus queues, in which each message is processed by a single consumer, topics and subscriptions provide a one-to-many form of communication, using a publish/subscribe pattern. It is possible to
 register multiple subscriptions to a topic. When a message is sent to a topic, it is then made available to each subscription to handle/process independently. A subscription to a topic resembles a virtual queue that receives copies of the messages that were sent to the topic. You can optionally register filter rules for a topic on a per-subscription basis, which allows you to filter or restrict which messages to a topic are received by which topic subscriptions.
