 ## Overview
 
 Azure Event Hubs provides an Apache Kafka endpoint on an event hub, which enables users to connect to the event hub using the Kafka protocol. You can often use an event hub's Kafka endpoint from your applications without any code changes. You modify only the configuration, that is, update the connection string in configurations to point to the Kafka endpoint exposed by your event hub instead of pointing to a Kafka cluster. Then, you can start streaming events from your applications that use the Kafka protocol into event hubs, which are equivalent to Kafka topics.

-The Event Hubs for Apache Kafka feature is one of three protocols concurrently available on Azure Event Hubs, complementing HTTP and AMQP. You can write with any of these protocols and read with any another, so that your current Apache Kafka producers can continue publishing via Apache Kafka, but your reader can benefit from the native integration with Event Hubs' AMQP interface, such as Azure Stream Analytics or Azure Functions. Conversely, you can readily integrate Azure Event Hubs into AMQP routing networks as a target endpoint, and yet read data through Apache Kafka integrations.

 One of the core tenets of Azure Event Hubs is the concept of **at-least once** delivery. This approach ensures that events will always be delivered. It also means that events can be received more than once, even repeatedly, by consumers such as a function. For this reason, it's important that the consumer supports the [idempotent consumer](https://microservices.io/patterns/communication-style/idempotent-consumer.html) pattern.

 Azure [Event Hubs Capture][capture-overview] enables you to automatically deliver the streaming data in Event Hubs to an [Azure Blob storage](https://azure.microsoft.com/services/storage/blobs/) or [Azure Data Lake Storage Gen 2](https://azure.microsoft.com/services/data-lake-store/) account of your choice. You can configure capture settings using the [Azure portal](https://portal.azure.com) when creating an event hub or for an existing event hub.

Event Hubs can process and store events, data, or telemetry produced by distributed software and devices.
