-# Azure Event Hubs for Apache Kafka ecosystems 
-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.

-### Key differences between Apache Kafka and Event Hubs
+## Key differences between Apache Kafka and Azure Event Hubs
 
 While [Apache Kafka](https://kafka.apache.org/) is software you typically need to install and operate, Event Hubs is a fully managed, cloud-native service. There are no servers, disks, or networks to manage and monitor and no brokers to consider or configure, ever. You create a namespace, which is an endpoint with a fully qualified domain name, and then you create Event Hubs (topics) within that namespace. 
 
 For more information about Event Hubs and namespaces, see [Event Hubs features](event-hubs-features.md#namespace). As a cloud service, Event Hubs uses a single stable virtual IP address as the endpoint, so clients don't need to know about the brokers or machines within a cluster. Even though Event Hubs implements the same protocol, this difference means that all Kafka traffic for all partitions is predictably routed through this one endpoint rather than requiring firewall access for all brokers of a cluster.   
 
 Scale in Event Hubs is controlled by how many [throughput units (TUs)](event-hubs-scalability.md#throughput-units) or [processing units](event-hubs-scalability.md#processing-units) you purchase. If you enable the [Auto-Inflate](event-hubs-auto-inflate.md) feature for a standard tier namespace, Event Hubs automatically scales up TUs when you reach the throughput limit. This feature work also works with the Apache Kafka protocol support. For a premier tier namespace, you can increase the number of processing units assigned to the namespace.

 Coming from building applications using Apache Kafka, it's also useful to understand that Azure Event Hubs is part of a fleet of services, which also includes [Azure Service Bus](../service-bus-messaging/service-bus-messaging-overview.md), and [Azure Event Grid](../event-grid/overview.md).

 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.

 The goal of Event Hubs for Apache Kafka is to provide access to Azure Event Hubs capabilities to applications that are locked into the Apache Kafka API and would otherwise have to be backed by an Apache Kafka cluster.
