An introduction to Event Hubs

Event Hubs are primarily designed to ingest large volumes of event and telemetry data in a high throughput manner from a variety of devices and services. They are similar in principle to Azure Queues and Azure Topics but with different characteristics and use cases. Although Azure Queues and Topics are used for enterprise messaging scenarios in which transaction support, dead-lettering, ordered delivery, and guaranteed delivery are of prime concerns, Event Hubs are biased toward very high throughput and event processing scenarios such as stream analytics.

Security in Event Hubs

When a device sends data to an Event Hub, it is normally to a virtual endpoint address defined by the publisher. A publisher requires a valid token to be passed with each message, which is a combination of a shared access signature (SAS) and a publisher name. The publisher name is normally the device's unique identifier.
