Azure Event Hubs Streaming Architecture

Azure Event Hubs is a big-data streaming platform and event ingestion service. It can receive millions of events per second from devices, applications, or other services and stream them to multiple consumers for real-time processing or later analysis. Event Hubs organizes incoming events into partitions within an event hub namespace. Partitions are ordered sequences of events; sending applications do not need to specify a partition directly, but can do so using a partition key to keep related events together. Each partition maintains the order of events, and all events within a partition are processed in the order they arrived.
