Microsoft Azure Event Hubs is a big data streaming platform and event ingestion service that is designed to handle millions of events per second. Notably, to ensure your Hybrid Cloud running on Azure Stack Hub is functional and up-to-date, updating an Event Hubs resource provider is a key process that should be mastered by every AZ-600 aspirant.
I. Updating process of Event Hubs resource provider
The process involves the following key steps:
- Step 1: Download the updated Event Hubs resource provider package.
To undertake this step, visit the Azure Stack Hub download page and download the updated resource provider package. - Step 2: Unzip the installer package.
After downloading the package, extract the files to a location of your preference on the Azure Stack Hub host. - Step 3: Run the installer.
This can be done by opening an elevated PowerShell command prompt, navigating to the directory where you unzipped the files, then executing .\Deploy.cmd. The installer will update the existing Event Hubs resource provider.
II. Post-Deployment Steps
After the deployment is successful, perform the following steps:
- Run tests to validate the updates.
- Configure the user plans and offers for the updated Azure Event Hubs RP.
- Check the Azure Stack Hub administrator portal to verify the status of the update.
III. Test the new Event Hubs resource provider
Upon successful updating of an Event Hubs resource provider, it’s necessary to validate its functionality using PowerShell and tenant API. You would need to create and manage Event Hubs namespaces, hubs, and event publishers.
Here’s a quick example of how to create a new Event Hubs namespace using PowerShell:
Login-AzAccount
Select-AzSubscription -SubscriptionId <subscription_id>
New-AzEventHubNamespace -ResourceGroupName <resource_group_name> -NamespaceName <namespace_name> -Location <location>
This code logs into Azure, selects the relevant subscription, then creates a new Event Hubs namespace in the specified resource group and location.
IV. Configure offers and plans
After updating the Azure Stack Hub’s Event Hubs resource provider and confirming its operation, it’s necessary to configure offers and plans for users. Azure Stack Hub allows you to package services into plans, that are then made available to users via offers. Update these plans and offers to reflect the new capabilities of the updated Event Hubs resource provider.
In conclusion, a comprehensive understanding and practical ability to update an Event Hubs resource provider are prerequisites for any IT expert preparing for the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam. Following the guide provided will ensure your Azure Stack Hub system is always current and functional, contributing towards a robust hybrid cloud environment.

True/False: An Event Hubs resource cannot be moved from one namespace to another.
- True
- False
Answer: True.
Explanation: Currently, an Event Hubs resource cannot be moved from one namespace to another. You would have to re-create the resource in the new namespace.
After updating an Event Hubs resource provider, it is always necessary to ____
