Event Hubs
Definition
Azure Event Hubs is a big data streaming platform for receiving and processing millions of events per second, enabling real-time analytics.
Use Cases
- Microsoft: Ingesting large volumes of telemetry and application logs for near-real-time monitoring and analytics in Azure. — Telemetry events are published to Azure Event Hubs, then processed by downstream consumers (for example, stream processing jobs and analytics services) using partitions and consumer groups to scale reads independently. (Enables scalable ingestion and parallel processing of high-volume event data to support operational monitoring and analytics.)
- Volkswagen Group: Vehicle and IoT telemetry ingestion for connected-car scenarios and downstream analytics. — Vehicle/edge telemetry is streamed into Azure using Event Hubs as an ingestion layer, then routed to analytics and storage services for processing and reporting. (Supports high-throughput ingestion of telemetry and decouples producers from multiple analytics consumers for scalable processing.)
Provider Equivalents

Frequently Asked Questions
- What's the difference between Azure Event Hubs and Azure Service Bus?
- Event Hubs is built for high-throughput event streaming (telemetry, logs, clickstreams) where you ingest large volumes and process them with one or more independent consumers. Service Bus is a message broker for enterprise messaging patterns (queues/topics) with features like sessions, transactions, dead-lettering, and request/response-style workflows. Use Event Hubs for streaming data pipelines; use Service Bus for application-to-application messaging and workflow integration.
- When should I use Azure Event Hubs?
- Use Event Hubs when you need to ingest and process large amounts of real-time data—such as IoT telemetry, application logs, website clickstream events, or security events—and you want multiple consumer applications to read the same stream independently. It’s a good fit when throughput and scalable ingestion matter more than per-message broker features like complex routing or transactions.
- How much does Azure Event Hubs cost?
- Pricing depends on the tier (Basic, Standard, Premium, or Dedicated), throughput capacity (such as throughput units or processing units, depending on tier), and features you enable. Additional costs can include capture to storage (if enabled), network egress, and downstream processing services. For accurate estimates, choose a tier based on required throughput, retention, and features, then use the Azure Pricing Calculator for your region.
