What is the AppFabric Service Bus [FAQ]

The Service Bus is the Azure service for connecting different applications and services through Azure. Several application design patterns are possible using the Service Bus:

Eventing – Notifying applications or devices of events and  passing instructions. At PDC an Azure ticketing application was demonstrated which allowed for physical tickets to be printed in several locations by notifying the devices through the Service Bus.

Service Remoting – Allow on-premise services and data to be put on the cloud.

Tunneling – Straightforward application to application communication.
