Scaling Capacity Units (CUs) in Azure Stack Hub |
Question
You are working on an Azure Stack Hub Integrated System.
Here, Event Hub clusters are created by the users depending upon the capacity units(CU)
Is it possible both to scale-in and scale-out the CUs.

A. B.Correct Answer: B
The system supports only CU Scale-out, not Scale-in.
CU scale-out (smaller to larger) is supported through the Create Event Hubs Cluster blade.
But CU Scale-in (larger to smaller) is not supported.

The correct answer is A. Yes, it is possible to both scale-in and scale-out the capacity units (CU) of Event Hub clusters on an Azure Stack Hub Integrated System.
Event Hub is a data streaming platform provided by Azure that enables real-time data ingestion at massive scale. Users can create Event Hub clusters on Azure Stack Hub Integrated System and scale them up or down based on their needs.
Scaling out involves adding more capacity units (CUs) to an Event Hub cluster to increase its capacity and handle more incoming data. Scaling in involves removing some of the CUs from an Event Hub cluster to decrease its capacity and reduce costs when the workload decreases.
Users can scale Event Hub clusters both manually and automatically. With manual scaling, users can add or remove CUs from the cluster using the Azure Stack Hub portal or PowerShell. With automatic scaling, users can define rules that automatically add or remove CUs based on certain conditions, such as the number of incoming messages or the size of the backlog.
In summary, Event Hub clusters on Azure Stack Hub Integrated System can be scaled both in and out, either manually or automatically, to meet changing workload requirements and optimize costs.
