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 premium 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.

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'll walk you through creating a 1 CU Event Hubs cluster through the Azure portal.

Prerequisites

To complete this quickstart, make sure that you have:

• An Azure account. If you don't have one, [purchase an account](https://www.microsoft.com/china/azure/index.html?fromtype=cn#azurefreeformStandard Pay-in-Advance Offer/) before you begin. This feature isn't supported with a trial subscription.
• Visual Studio 2017 Update 3 (version 15.3, 26730.01) or later.
• .NET Standard SDK, version 2.0 or later.
• Created a resource group.

Create an Event Hubs Dedicated Cluster

An Event Hubs cluster provides a unique scoping container in which you can create one or more namespaces.

To create a cluster in your resource group using the Azure portal, 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 Event Hubs Clusters page, select + Create on the toolbar.

3. On the Create Cluster page, configure the following settings:

   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. Notice that the Support Scaling option is set to Enabled.

   5. Select a location for the cluster. If your preferred region is grayed out or it's temporarily out of capacity. Submit a support request to the Event Hubs team for further assistance.

   6. 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.

      

4. On the Tags page, configure the following:

   1. Enter a name and a value for the tag you want to add. This step is optional.

   2. Select the Review + Create button.

      Important

      You won't be able to delete the cluster for at least 4 hours after you create it. Therefore, you will be charged for a minimum 4 hours of usage of the cluster..

5. On the Review + Create page, review the details, and select Create.

   

6. After the creation is successful, select Go to resource to navigate to the home page for your Event Hubs cluster.

Create a namespace and event hub within a cluster

1. To create a namespace within a cluster, on the Event Hubs Cluster page for your cluster, select +Namespace from the top menu.

   

2. On the Create a namespace page, do the following steps:

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

   2. The namespace inherits the following properties:

      1. Subscription ID
      2. Resource Group
      3. Location
      4. Cluster Name

   3. Select Create to create the namespace. Now you can manage your cluster.

      

3. Once your namespace is created, you can create an event hub as you would normally create one within a namespace.

Delete a dedicated cluster

1. To delete the cluster, select Delete from the top menu.

   Important

   You won't be able to delete the cluster for at least 4 hours after you create it. Therefore, you will be charged for a minimum 4 hours of usage of the cluster. For more information on pricing, see Event Hubs - Pricing.

2. A message will appear confirming your wish to delete the cluster.

3. Type the name of the cluster and select Delete to delete the cluster.
