determining hardware and operating costs of the virtualized computer resources;
identifying which cost centers use each virtualized computing resource;
allocating a threshold level of CPU usage, memory usage, storage usage, and network usage for each identified cost center;
setting a base rate for each identified cost center for usage of the virtualized computing resources at or below the allocated threshold level;
setting over usage rates for CPU usage, memory usage, storage usage, and network usage that exceeds the threshold level for a cost center;

setting rates for at least CPU usage, memory usage, storage usage, and network usage; and
calculating a rate that needs to be charged to recover costs in view of at least an amount spent on hardware, a time period in which the amount needs to be recovered, how many cost centers use the hardware, and an average usage of each virtualized computing resource, wherein the average usage is updated if the average usage increases;
(b) selecting, via the device, a rate level in a hierarchy of rate levels at which to charge the rate, wherein the rate levels in the hierarchy include virtual machine, host, business service, customer, and global, wherein a business service associates a group of virtual machines that provide a single service or distributed application;
