新兴的云计算基础设施基于后付费原则按需提供计算资源。例如，RESERVOIR项目开发了一个能够提供弹性容量的基础设施，该容量可以自动增加或减少，以经济高效地履行既定的服务水平协议。该基础设施还使数据中心能够通过从协作数据中心分包额外资源来扩展其总容量，从而使基础设施成为云联盟。对于记账和计费，这样的基础设施需要新颖的方法来对随时间变化的容量以及在物理机器之间甚至在数据中心之间迁移的服务（或者更准确地说是虚拟机）执行记账。对于计费，需要新的方法来同时管理后付费和预付费支付方案，以用于响应于用户需求而随时间变化的容量。在本文中，我们概述了使用场景和一组这样的基础设施的要求，并提出了一个会计和计费体系结构中使用的水库。尽管此体系结构的主要重点是资源使用者和基础设施提供者之间的记帐和计费，但也考虑了将来对站点间计费的支持。
Emerging Cloud computing infrastructures provide computing resources on demand based on postpaid principles. For example, the RESERVOIR project develops an infrastructure capable of delivering elastic capacity that can automatically be increased or decreased in order to cost-efficiently fulfill established Service Level Agreements. This infrastructure also makes it possible for a data center to extend its total capacity by subcontracting additional resources from collaborating data centers, making the infrastructure a federation of Clouds. For accounting and billing, such infrastructures call for novel approaches to perform accounting for capacity that varies over time and for services (or more precisely virtual machines) that migrate between physical machines or even between data centers. For billing, needs arise for new approaches to simultaneously manage postpaid and prepaid payment schemes for capacity that varies over time in response to user needs. In this paper, we outline usage scenarios and a set of requirements for such infrastructures, and propose an accounting and billing architecture to be used within RESERVOIR. Even though the primary focus for this architecture is accounting and billing between resource consumers and infrastructure provides, future support for inter-site billing is also taken into account.
