Introduction to Azure Event Hubs

Welcome to the world of real-time data streaming with Azure Event Hubs! This tutorial series will guide you through understanding and utilizing this powerful cloud service for ingesting massive amounts of data.

What is Azure Event Hubs?

Azure Event Hubs is a highly scalable data streaming platform and event ingestion service. It can receive and process millions of events per second. Event Hubs allows you to ingest data from a wide variety of sources, such as web applications, mobile devices, IoT sensors, and server logs. It then makes this data available for processing and analysis by various downstream services.

Key Concepts

• Event Producers

  Applications or devices that send (publish) event data to an Event Hub. This can be anything from a web server generating clickstream data to an IoT device sending sensor readings.

• Event Hubs

  The central entity within the Event Hubs namespace that receives events. An Event Hub is a partitioned stream. Partitions are ordered, immutable sequences of events.

• Event Consumers

  Applications that read (subscribe) to event data from an Event Hub. Consumers can read events in real-time as they arrive or process historical data.

• Consumer Groups

  An application or service using Event Hubs can have multiple independent, read-only views of the data in an Event Hub. Each application using Event Hubs is called a consumer group.

• Partitions

  Event Hubs is a partitioned service. Each partition is an ordered sequence of events. Event Hubs ensures that events sent to the same partition are stored and delivered in order. Partitioning allows for parallel processing of event streams.

Why Use Event Hubs?

Event Hubs is ideal for scenarios involving:

• Ingesting telemetry data from millions of devices.
• Processing clickstream data for web applications.
• Collecting logs from various services for analysis.
• Building real-time dashboards and monitoring systems.
• Feeding data into machine learning pipelines.

Getting Started

To begin working with Azure Event Hubs, you'll typically need:

1. An Azure subscription.
2. An Event Hubs namespace created in your Azure subscription.
3. An Event Hub within that namespace.

In the next tutorials, we'll walk you through creating an Event Hub, sending data to it, and then reading that data using consumer groups.
