How to apply license quantities for Azure VMSS

Question

I am using Windows Azure VMSS and have fixed a minimum of 3 instances without using auto-scaling. How is the Windows license core count calculated in this case? If I am using a 2-core SKU, does that mean I will consume 6 cores in total for the 3 instances, or does each VMSS resource only consume 2 cores?

Answer 1

Hello,

When using Azure Virtual Machine Scale Sets (VMSS), each instance within the scale set operates as an individual virtual machine. Therefore, the licensing and core count apply to each instance separately.

In your scenario:

You have a fixed minimum of 3 instances in your VMSS.

You are using a 2-core SKU.

This means each of your instances has 2 cores. Therefore, the total core count for licensing purposes would be:

2 cores per instance * 3 instances = 6 cores

So, yes, you would consume a total of 6 cores for the 3 instances combined. Each VM instance is counted separately when calculating the total number of cores used.
