Active Devices are devices eligible to receive notifications and are defined as unique registration IDs, channel URI (Uniform Resource Identifier), or device token. Note that a physical device can count as multiple Active Devices for Notification Hubs.
Pushes include all notifications delivered to the platform notification services (e.g. Windows Notification Service, Apple Push Notification Service, Google Cloud Messaging, Microsoft Push Notification Service). Push allowance is prorated and capped on a daily basis.
In the Basic and Standard tier, the Pushes per month limit is based on the number of Units purchased. A Unit represents an incremental allowance for Pushes per month you can purchase. Allowances are enforced for the total Active Devices (Free tier only) and Pushes used by all Notification Hubs for different applications within a Namespace. A Namespace is a grouping mechanism and may contain multiple Notification Hubs. Windows Azure Management Portal allows customers to scale up to 50 units per Namespace in the Standard tier. Please contact Support if you need additional capacity for your namespace.
Notification Hubs API calls including Send, Registration Queries, Updates, and Deletions are included in the price, limited to 500,000 per month in the Free tier, 2 million per month in the Basic tier, and 20 million per unit per month in the Standard tier to prevent abuse. Allowances for Pushes and API calls are prorated and capped on a daily basis.
Note: Notification Hubs is now offering a private preview of high-volume individual push notifications. If you are interested using Notification Hubs for unicast/1-to-1 push notifications at high volume (greater than 300 million pushes per month) and low cost, please contact us for details regarding our new Private Preview offer.
