Quickstart: Create a dedicated Event Hubs cluster using Azure portal

Event Hubs clusters offer single-tenant deployments for customers with the most demanding streaming needs. This offering has a guaranteed 99.99% SLA and is available only on our Dedicated pricing tier. An Event Hubs cluster can ingress millions of events per second with guaranteed capacity and subsecond latency. Namespaces and event hubs created within a cluster include all features of the standard offering and more, but without any ingress limits. The Dedicated offering also includes the popular Event Hubs Capture feature at no additional cost, allowing you to automatically batch and log data streams to Azure Blob Storage or Azure Data Lake Storage Gen 1.

Dedicated clusters are provisioned and billed by Capacity Units (CUs), a pre-allocated amount of CPU and memory resources. You can purchase 1, 2, 4, 8, 12, 16 or 20 CUs for each cluster. In this quickstart, we will walk you through creating a 1 CU Event Hubs cluster through the Azure portal.

Note

This self-serve experience is currently available in preview on Azure Portal. If you have any questions about the Dedicated offering, please reach out to the Event Hubs team.

Create an Event Hubs Dedicated Cluster

An Event Hubs cluster provides a unique scoping container in which you can create one or more namespaces. In this Preview phase of the portal self-serve experience, you can create 1 CU clusters in select regions. If you need a cluster larger than 1 CU, you can submit an Azure support request to scale up your cluster after its creation.

To create a cluster in your resource group using the Azure portal, please complete the following steps:

  1. Follow this link to create a cluster on Azure portal. Conversely, select All services from the left navigation pane, then type in "Event Hubs Clusters" in the search bar and select "Event Hubs Clusters" from the list of results.

  2. On the Create Cluster page, configure the following:

    1. Enter a name for the cluster. The system immediately checks to see if the name is available.

    2. Select the subscription in which you want to create the cluster.

    3. Select the resource group in which you want to create the cluster.

    4. Select a location for the cluster. If your preferred region is grayed out, it is temporarily out of capacity and you can submit a support request to the Event Hubs team.

    5. Select the Next: Tags button at the bottom of the page. You may have to wait a few minutes for the system to fully provision the resources.
