Hi @Gary BORTHWICK ,
as far as I know the chassis asset tag value
7783-7084-3265-9085-8269-3286-77 could be Azure or Azure Stack.
There is no guarantee the asset tag value for Azure/Azure Stack will be same in the future.
But for now this is a possible solution to classify VMs in Azure.
Another option to identify Azure VMs could be the IP address of an VM if there is no overlapping IP address ranges in Azure and on-premises.
