Chapter 16

Chargeback

This chapter discusses the topic of how to measure the usage of a cloud or shared infrastructure. This is not a new concept, but rather an old idea with a new application: the cloud. It mainly focuses on the issue of cloud operations. The idea in emphasizing chargeback is to understand how the cloud cost should be allocated for different Line of Business (LoB) units. The chargeback exercise makes the cost model assumptions much more rational and objective. The ultimate goal of a chargeback is to make the cloud cost as transparent as possible.
