Billing Policy

considered for billing. The actual usage of the chargeable computing resources
is ignored.

the virtual machines is determined. The total cost is then calculated by using
the base rates set in the cost model and the actual used units of the chargeable
computing resources.

for a virtual machine. vCenter Server allows only CPU and memory
reservation. This reserved capacity of CPU and memory along with the actual
utilization of other chargeable computing resources is used for calculating the
