Azure Event Hubs is a highly scalable data streaming platform and event ingestion service that receives and processes events. Azure Event Hubs can ingest and process large volumes of events with low latency and high reliability. It is a managed service that can handle message streams from a wide range of connected devices and systems.

Any entity that sends data to an event hub is an event publisher. Event publishers can publish events using HTTPS or Kafka 1.0 and later. Event publishers use a Shared Access Signature (SAS) token to identify themselves to an event hub and can have a unique identity or use a common SAS token.
