Service Bus Notification Hubs are an intrinsic feature of Windows Azure Service Bus and are different from other push notification services in four key areas:
•Complete client registration management. Your backend application does not need to worry at all about device-ids or channels or other particulars of push notifications and doesn’t need to cooperate in management. It doesn’t even have to be a web app that’s publicly accessible.
•Platform independence. Service Bus Notification Hubs allow cross-platform push notifications so that iOS Alerts and Windows Live Tiles can be targeted with a single event message.
•Broadcast and tag-based Multicast – Service Bus Notification Hubs are optimized around automatic notification broadcast to many thousand devices with low latency. One message in, thousands of notifications out.
•Mass customization – Notification Hub notification templates allow for customization of notification delivery for each individual registration, allowing each instance of a client App to choose how it wants to receive events.
