What is Azure Event Hub?

Azure Event Hubs is a fully managed, real-time data ingestion service that's scalable and can stream millions of events per second from any source. It is often used for big data streaming scenarios, ingesting data from IoT devices, and capturing event data for real-time analytics and archiving. Event Hubs acts as a highly scalable 'front door' for a data pipeline, often feeding data into services like Azure Stream Analytics, Azure Databricks, and Azure Data Lake Storage.
