Notification Hubs
Azure Notification Hubs is a messaging service that allows you to send push notifications to iOS, Android, Windows, and Kindle devices from any backend. It simplifies mobile app development by handling the complex infrastructure required to deliver messages to various platforms efficiently.
Choose this service when you need a centralized solution for cross-platform mobile notifications. Be aware that there is no free tier available, so you will incur costs immediately based on the pay-as-you-go pricing model without any initial usage allowance.
