To support chargeback, the virtual environment and the chargeback solution must provide ways to measure

resource usage and associate the usage with a specific pricing model. The chargeback solution must also

support the use of different pricing models so as to charge the various departments or cost centers

differently.

A chargeback solution for a virtual environment defines a hierarchy with different types of entities such as

departments, divisions, business units, cost centers, physical servers, virtual machines, and so on. For each

entity type, a pricing model is defined that determines the rate for each unit of a resource utilized. The

chargeback solution determines the resource usage by using either utilization-based metering or allocation-

based metering of virtual machines. The metered parameters are then associated with the designated

entities, and the pricing model defined for that entity along with specific chargeback formulas are used as

part of the overall chargeback solution.

Overview of vCenter Chargeback Manager

Determining the resource utilization and calculating the corresponding cost for a virtual environment that

uses VMware vSphere typically involves VMware professional services’ work or use of partner solutions.

These solutions are built using custom methods for VMware vSphere resource data collection and

chargeback cost calculation for organizations.

vCenter Chargeback Manager is an end-to-end cost reporting solution for virtual environments that use

VMware vSphere. This Web-based application interacts with the vCenter Server Database to retrieve usage

information, calculates the cost by using the defined chargeback formulas, and generates cost and usage

reports. Figure 1-1 shows how vCenter Chargeback Manager interacts with various components of a virtual

environment using VMware vSphere.
