Introduction to vCenter Chargeback

Manager 1

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

vSphere. vCenter Chargeback Manager can also be used with VMware vCloud Director. Before you install

and start using vCenter Chargeback Manager, an understanding of what is chargeback and about

chargeback solutions for a virtual environment would be helpful.

This chapter includes the following topics:

What Is Chargeback

Chargeback is a mechanism to account for the operational costs involved in providing and maintaining an

IT infrastructure, including the costs for IT services and applications. Measuring resource utilization and

calculating the corresponding IT operational cost enables you to account for the IT resources utilized and

bill for the services provided.

In a non-virtual environment, a physical server and the associated resources like the applications running

on it can be easily mapped to the department using them, making the billing for such resource utilizations

relatively easy. Also, costs incurred due to maintenance and licensing can be directly associated to a

department, thereby enabling you to calculate the complete IT operational costs.

In a virtual environment, however, the task of calculating the IT operational cost for each department

becomes very difficult. Multiple virtual machines run on a physical server, which might be shared across

different departments or cost centers in an organization. As a result, resource utilization for this server and,

therefore, the cost incurred cannot be directly associated to any single department or cost center. The

difficulty in accounting gets further compounded when applications and services get shifted over time to

different servers, based on the load and available infrastructure resources.

Chargeback Solution for Virtual Environments

In a virtual environment, a chargeback solution requires a flexible metering system that can account for the

utilization of resources shared across the organization.

These measurements can be based on allocation or actual usage of individual servers and resources. In the

case of VMotion, DRS, or HA being enabled, the measurements could be based on the allocation or actual

usage of resource pools.
