Windows AHB on scale sets

Question

When applying Windows AHB to VM scale sets is it required to License per scales set or per the instances within the scale set? Baring in mind some of the scale sets can scale out to large numbers of instances.

Many thanks for any feedback!

Hello, @Grant Algar !

How does Azure Hybrid Benefit (AHB) work on Windows Server VM Scale Sets?

For Windows Server, you can apply AHB to a VM Scale Set:

You can also apply Azure Hybrid Benefit for Windows Server on virtual machine scale set as well.

Consumed Cores per Virtual Machine Scale Sets are measured however the usual minimum of 8 cores still applies. This becomes a bit clearer when we look at a recent AHB management blog with a VMSS example:

Here you can see where AHB is and is not enabled, as well as lower priority that is given to VMSS with fewer than 8 cores:
