Quickstart: Create an event hub using Azure portal
Azure Event Hubs is a Big Data streaming platform and event ingestion service that can receive and process millions of events per second. Event Hubs can process and store events, data, or telemetry produced by distributed software and devices. Data sent to an event hub can be transformed and stored using any real-time analytics provider or batching/storage adapters. For detailed overview of Event Hubs, see Event Hubs overview and Event Hubs features.
In this quickstart, you create an event hub using the Azure portal.
To complete this quickstart, make sure that you have:
- Azure subscription. If you don't have one, create a free account before you begin.
Create a resource group
A resource group is a logical collection of Azure resources. All resources are deployed and managed in a resource group. To create a resource group:
Sign in to the Azure portal.
In the left navigation, select Resource groups. Then select Add.
For Subscription, select the name of the Azure subscription in which you want to create the resource group.
Type a unique name for the resource group. The system immediately checks to see if the name is available in the currently selected Azure subscription.
Select a region for the resource group.
Select Review + Create.
On the Review + Create page, select Create.
Create an Event Hubs namespace
An Event Hubs namespace provides a unique scoping container, in which you create one or more event hubs. To create a namespace in your resource group using the portal, do the following actions:
In the Azure portal, and select Create a resource at the top left of the screen.
Select All services in the left menu, and select star (
*) next to Event Hubs in the Analytics category. Confirm that Event Hubs is added to FAVORITES in the left navigational menu.
Select Event Hubs under FAVORITES in the left navigational menu, and select Add on the toolbar.
On the Create namespace page, take the following steps:
Select the subscription in which you want to create the namespace.
Select the resource group you created in the previous step.
Enter a name for the namespace. The system immediately checks to see if the name is available.
Select a location for the namespace.
Leave the throughput units settings as it is. Throughput units are pre-purchased units of capacity. To learn about throughput units, see Event Hubs scalability.
Select Review + Create at the bottom of the page.
On the Review + Create page, review the settings, and select Create. Wait for the deployment to complete.
On the Deployment page, select Go to resource to navigate to the page for your namespace.
Confirm that you see the Event Hubs Namespace page similar to the following example:
Azure Event Hubs provides you with a Kafka endpoint. This endpoint enables your Event Hubs namespace to natively understand Apache Kafka message protocol and APIs. With this capability, you can communicate with your event hubs as you would with Kafka topics without changing your protocol clients or running your own clusters. Event Hubs supports Apache Kafka versions 1.0 and later. For more information, see Use Event Hubs from Apache Kafka applications.
Create an event hub
To create an event hub within the namespace, do the following actions:
On the Event Hubs Namespace page, select Event Hubs in the left menu.
At the top of the window, select + Event Hub.
Type a name for your event hub, then select Create.
The partition count setting allows you to parallelize consumption across many consumers. For more information, see Partitions.
The message retention setting specifies how long the Event Hubs service keeps data. For the maximum limits for this setting, see Quotas and limits.
You can check the status of the event hub creation in alerts. After the event hub is created, you see it in the list of event hubs.
In this article, you created a resource group, an Event Hubs namespace, and an event hub. For step-by-step instructions to send events to (or) receive events from an event hub, see these tutorials:
