Quickstart: Create a Dedicated Azure Event Hubs cluster using Azure portal

  • Straipsnis

Event Hubs clusters offer single-tenant deployments for customers with the most demanding streaming needs. This offering has a guaranteed 99.99% SLA, which is available only in 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 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 up to 10 CUs for a cluster in the Azure portal. If you need a cluster larger than 10 CU, you can submit an Azure support request to scale up your cluster after its creation. In this quickstart, we'll walk you through creating a 1 CU Event Hubs cluster through the Azure portal.

Note

  • The Dedicated tier isn't available in all regions. Try to create a Dedicated cluster in the Azure portal and see supported regions in the Location drop-down list on the Create Event Hubs Cluster page.
  • This Azure Portal self-serve experience is currently in preview. If you have any questions about the Dedicated offering, reach out to the Event Hubs team.

Prerequisites

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

Warning

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.
