Thanks Einav.

Mitja, 

Compute resources (CPU, RAM) are being consumed when the VM is running.
So yes, you can create how many VMs you'd like as long as you don't exceed storage limit,
but run VMs only as many as your quota permit (cpu and memory limitations).

The difference between storage to compute resources is that storage is being consumed when the disks are copied
while memory and cpu consumed when the VM is running.

Thanks, 
Gilad.
