摘要
IaaS服务的商用化使得对计费模型的研究成为学术界和工业界关注的热点之一.合理公平的计费模型对服务提供商和服务消费者来说都至关重要,现有典型的IaaS服务计费策略多数只侧重服务提供商或服务消费者一方的利益,因此,提出一种基于服务等级协议(service level agreement,SLA)与投资回报率(return on investment,ROI)结合的计费模型来同时保证提供商和消费者双方利益.实验证明,该计费模型对用户和服务商来说都相对比较公平,在二者之间取得了平衡.
IaaS service leads to make the study of pricing model as one of the hot spots in academia and industry.Reasonable and fair pricing model is crucial for service providers and service consumers,and existing typical IaaS service pricing strategies most only focus on the service provider or the interests of the consumers,therefore,put forward a pricing model based on combining SLA and ROI to ensure both providers and consumers interests at the same time.The experiments show that the pricing model for users and service providers is relatively fair and achieves a balance between the two.
