基于效用的云计算动态资源计费策略

Resource dynamic pricing strategy based on utility in cloud computing

通过对服务等级协议(Service level agreement,SLA)内容监测及用户评估的分析,扩展了现有SLA内容样式。提出了改进的SLA性能管理机制,从而建立了新的计费管理框架。实验结果表明:本文所提出的计费策略能够最大程度地满足SLA的协商需求,能够为用户节省费用,最大化用户满意度。

In this article, the content style of Service Level Agreement （SLA） is expanded and an improved performance management mechanism of SLA is proposed, which are based on SLA content monitoring and analysis o{ user evaluation. Accordingly, a new pricing management framework is established and a resource dynamic pricing strategy is proposed based on utility. Experiment results show that the proposed pricing strategy maximally meets the demand for the SLA negotiation, which saves users＇ cost and maximizes users＂ satisfaction.
