It can receive and process millions of events per second. You can use Event Hubs in various scenarios such as telemetry data collection, log streaming, clickstream analysis, and integration with other data analytics solutions. In the context of AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub, we will focus on how to deploy an Event Hubs resource provider.
Deploying Event Hubs on Azure Stack Hub
The Azure Stack Hub is Microsoft’s hybrid cloud platform, providing a consistent Azure experience on premises. Deploying the Event Hubs resource provider on Azure Stack Hub involves a couple of steps.
Prerequisites
Before starting the deployment, make sure the following prerequisites are met:
- You need to be running Azure Stack Hub version 2002 or later.
- An active Azure subscription is required.
- The Event Hubs resource provider package, which can be downloaded from the Azure Stack Hub Marketplace.
Deployment Steps
Following are the steps needed to deploy an Event Hubs resource provider:
- Download the Provider’s Package: From the Azure Stack Hub admin portal, go to the marketplace management and download the Event Hubs resource provider package.
- Register the Resource Provider:Once the package is downloaded, the next step is to register the Event Hubs resource provider to your Azure Stack Hub to let it be used within the environment. You can do this by running the following PowerShell command:
Register-AzsResourceProvider -ProviderNamespace Microsoft.EventHub.Azurestack
- Access Event Hubs:Now, the Event Hubs should be available from the main dashboard of Azure Stack Hub portal. You can create and manage Event Hubs namespaces and event hubs.
- Deploying Event Hubs instances:To use Event Hubs, you first need to create a namespace, and then create an event hub under that namespace. Below is an example of a CLI command that you can run to create a namespace:
az eventhubs namespace create –name MyNamespace –resource-group MyResourceGroup
After the namespace is in place, execute the following CLI command to create an event hub:
az eventhubs eventhub create –name MyEventHub –namespace-name MyNamespace –resource-group MyResourceGroup
Comparison
| Azure Event Hubs | Azure Stack Hub – Event Hubs |
|---|---|
| Fully managed by Azure | Managed by the Azure Stack Hub operator |
| Available globally | Availability depends on Azure Stack Hub deployment |
| Integrates seamlessly with other Azure services | Integration possibilities depend on services available on Azure Stack Hub |
In conclusion, deploying an Event Hubs resource provider in an Azure Stack Hub environment isn’t a complex task. It allows you to benefit from Event Hubs capabilities in a hybrid cloud setup aligned with Azure practices. During the process, always ensure you have the necessary permissions and prerequisites met to ensure a smooth deployment. The entire process also fits in well with the objectives of the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam, making it a useful topic of understanding.
