What is a Push Notification Hub?
Fast broadcast to millions of devices. Azure Notification Hubs is a massively scalable mobile push notification engine for quickly sending millions of notifications to iOS, Android, Windows, or Kindle devices, working with APNs (Apple Push Notification service), GCM (Google Cloud Messaging), WNS (Windows Push Notification Service), and more.

Azure Notification Hubs provide an easy-to-use and scaled-out push engine that enables you to send notifications to any platform (iOS, Android, Windows, etc.) from any back-end (cloud or on-premises). Notification Hubs works great for both enterprise and consumer scenarios. Here are a few example scenarios:
•Send breaking news notifications to millions with low latency.
•Send location-based coupons to interested user segments.
•Send event-related notifications to users or groups for media/sports/finance/gaming applications.
•Push promotional contents to applications to engage and market to customers.
•Notify users of enterprise events such as new messages and work items.
Push notifications are a form of app-to-user communication where users of mobile apps are notified of certain desired information, usually in a pop-up or dialog box on a mobile device. Users generally choose to view or dismiss the message; choosing the former opens the mobile application that communicated the notification. Some notifications are silent - delivered behind the scenes for the app to process and decide what to do.
Push notifications are vital for consumer apps in increasing app engagement and usage, and for enterprise apps in communicating up-to-date business information. It's the best app-to-user communication because it is energy-efficient for mobile devices, flexible for the notifications senders, and available when corresponding applications are not active.

Push notifications are delivered through platform-specific infrastructures called Platform Notification Systems (PNSes). They offer basic push functionalities to deliver a message to a device with a provided handle, and have no common interface. To send a notification to all customers across the Android, iOS, and Windows versions of an app, the developer must work separately with Apple Push Notification Service (APNS), Firebase Cloud Messaging (FCM), and Windows Notification Service (WNS).
At a high level, here is how push works:
1.An application wants to receive a notification, so it contacts the PNS for the target platform on which the app is running and requests a unique and temporary push handle. The handle type depends on the system (for example, WNS uses URIs while APNS uses tokens).
2.The client app stores this handle in the app backend or provider.
3.To send a push notification, the app backend contacts the PNS using the handle to target a specific client app.
4.The PNS forwards the notification to the device specified by the handle.
PNSes are powerful. However, they leave much work to the app developer to implement even common push notification scenarios, such as broadcasting push notifications to segmented users.
Sending push notifications requires complex infrastructure that is unrelated to the application's main business logic. Some of the infrastructure challenges are:
•Platform dependency
•The backend requires complex and hard-to-maintain platform-dependent logic to send notifications to devices on various platforms, as PNSes are not unified.
•Scale
•Per PNS guidelines, device tokens must be refreshed on every app launch. The backend deals with a large amount of traffic and database access just to keep the tokens up-to-date. When the number of devices grows to hundreds, thousands, or millions, the cost of creating and maintaining this infrastructure is massive.
Notification Hubs eliminates all complexities associated with sending push notifications on your own from your app backend. Its multi-platform, scaled-out push notification infrastructure reduces push-related coding and simplifies your backend. With Notification Hubs, devices are merely responsible for registering their PNS handles with a hub, while the backend sends messages to users or interest groups, as shown in the following figure:
Notification Hubs is your ready-to-use push engine with the following advantages:
•Cross platforms
•Support for all major push platforms.
•A common interface to push to all platforms in platform-specific or platform-independent formats with no platform-specific work.
•Device handle management in one place.

Azure Notification Hubs has two resource levels: hubs and namespaces. A hub is a single push resource that can hold the cross-platform push information of one app. A namespace is a collection of hubs in one region. Recommended mapping matches one namespace with one app. Within a namespace, you can have a production hub that works with your ...
