With pay-per-use pricing models, elastic scaling of resources, and the usage of shared virtualized infrastructure, the Cloud offers more efficient use of capital, great cost reductions, and breakthrough agility. Yet, this new IT provisioning model profoundly changes the economics of IT. It turns out that to leverage the Cloud advantages, to realize the possible cost reductions, and to provide business consumers with the flexibility of pay-per-use, organizations have to introduce Cloud-friendly chargeback models. That is, they have to allocate IT service costs to business users in a way that reflects service consumption. To help organization transition to a Cloud environment, this work provides answers to three questions. Firstly, it explains how the Cloud impacts chargeback and why it requires new chargeback models. Secondly, it reveals what factors impact the design of a successful chargeback model for a Cloud environment. Finally, it proposes a Cloud-Chargeback Meta-Model (CCMM) that describes the structure of a chargeback model for Cloud services, offers guidelines how make the most important chargeback decisions and how to charge for the different types of Cloud services. The findings presented below are based on an extensive overview of the management and scientific literature, and on interviews and
