Abstract

Cloud resources are provided to users on request and the bills are generated on the basis of resources actually consumed. Therefore, during periods of low demand, the idle resources may cause financial loss to Cloud Providers (CPs). While in peak load, user’s request may be rejected due to insufficient resources. To manage this issue of under or over provisioning of resources, different CPs may voluntarily unite and efficiently utilize the resources in accordance with some agreement among them, thus creating a Federation of Clouds. Accounting and Billing of resources in such an environment is an important issue as inappropriate calculation of bills may either cause loss to CPs due to undercharging or to users by overcharging them. Taking this into consideration, this paper aims: To perform a literature review of the existing accounting and billing solutions in single CP and Federated Cloud Environment and; Identify the requirements and limitations of the existing accounting and billing methods so as to justify and support the need of a new framework for Accounting and Billing of infrastructural resources in Federation of Clouds.
