Question

What is Azure Event Hubs?

Solution

Azure Event Hubs is Azure's managed big-data ingestion service for event streams. Producers send events; consumers read them with consumer groups. It is the Azure analogue people compare to Kafka / Kinesis.

  Event Hubs namespace / hub

      +--> Stream Analytics
      +--> Spark / Databricks / Flink
      +--> Capture to ADLS (optional)

Key ideas

  • Partitions spread throughput (Kafka-like)
  • Consumer groups let multiple apps read independently
  • Event Hubs Capture can land raw events to ADLS/Blob on a schedule
  • Kafka protocol support exists so some Kafka clients can talk to Event Hubs

Vs Kafka (short)

Event Hubs is fully managed Azure PaaS with partition + consumer group concepts. Kafka is the open ecosystem; Event Hubs is the Azure-native front door (or you run Kafka on Azure separately).

Interview tip: "Event Hubs = Azure managed event ingestion with partitions and consumer groups." Mention Capture-to-lake as a classic DE pattern.
