What is a subscription? What is a namespace? What is a hub?

An Azure subscription helps you organise access to cloud service resources, where Notification Hubs is a resource. A namespace is a grouping mechanism that may contain multiple notification hubs and sits in one region. A hub is an engine that simplifies push and sends notifications to cross-platform applications with features in Notification Hubs.

  • Pushes include all notifications delivered to the platform notification services (e.g. Windows Notification Service, Apple Push Notification Service, Google Cloud Messaging and Microsoft Push Notification Service).

  • Active devices are devices eligible to receive notifications. They are defined as unique registration IDs for devices using Google Cloud Messaging or Amazon Device Messaging, channel uniform resource identifiers (URI) for devices using Windows notification service or Microsoft push notification Service, or device tokens for devices using Apple push notification service.

  • Both basic and standard tiers do not require auto-scaling. Customers can use an unlimited amount of pushes at published rates.

  • There are no daily push quotas.

  • All new registrations against any hubs within the namespace in which the active device quota has been reached will be interrupted.

  • Go to the management portal, ServiceBus, and click on your namespace, then your notification hub. Under the Scale tab, you will be able to change your Notification Hubs service tier.
