摘要

预付费是云服务计费的重要选项,为服务提供商和客户提供了有效的财务控制。然而,它必须得到实时信用检查和成本计算的支持。这些实时操作消耗提供者的网络资源,并带来很高的开销。为了解决这个问题,我们提出了一个可扩展的计费解决方案,其中在构成云系统的每个集群中托管一个计费组件。我们的每个会计组件都根据服务包的计算间隔来监督服务消费,服务包由托管在集群中的所有服务组成,并由一个客户同时消费。当客户在一个集群中的信用不足以补偿进一步的使用时,将重新分配信用,并根据服务消耗执行分配。这项工作旨在降低预付费服务的成本,并确保服务的提供不受收费部分的阻碍。此外,我们进行了理论和实验分析,表明这项工作可以为存储云中的长期服务提供廉价的会计解决方案。

A Scalable Accounting Solution for Prepaid Services in Cloud Systems
Prepaid charging, an essential option for the accounting of cloud services, provides effective financial control for both service providers and customers. However, it has to be supported by real-time credit checking and cost calculation. These real-time actions consume resources of the providers' network and impose high overhead. To tackle this issue, we present a scalable accounting solution in which an accounting component is hosted in every cluster constituting a cloud system. Each of our accounting component supervises service consumptions based on a calculated interval of a service bundle that is composed of all services hosted in a cluster and consumed by one customer simultaneously. Credit will be re-allocated when a customer's credit in one cluster is not enough to compensate further usage, and the allocation is performed based on service consumptions. This work is intended to reduce the cost of prepaid services and to ensure service provision is not hampered by the charging part. Additionally, we perform theoretical and experimental analyses that indicate this work can provide an inexpensive accounting solution for the long-lived services in storage clouds.
