Please note that I'm new and just started to learn Azure since last two weeks. Well now, I have been given a list VMs with its own specs, for examples:
VM1
Type: Active directory (what does that mean?, isn't it different from a VM)
Virtual disk type: fixed
HDD Size: 80GB, Utilization: 30 GB
Guest : Windows Server 2016 Standard
Ram: 8, type: Static
vCPU: 2
VM2
Type: Web/DB
Virtual disk type: differencing (what should I do with this information?)
HDD Size: 150GB, Utilization: 9.82 GB
Guest : Windows Server 2012 R2 Standard
Ram: 4, type: Static
vCPU: 2
I've watched youtube and tutorials on calculating a simple VM but they never considered or mentioned any specifications as above. Thus, I really have no idea how to generate estimation based on these two examples.
