通过总结所有IaaS(infrastructure as a service)云服务定价的方法,明确了pay-per-use和subscription是目前业界普遍采用的两种定价方法,分析了IaaS 云服务定价影响因素,并把IaaS 云计算服务的五大基础参数(初始投资、合同期限、资源折旧、服务质量和资源年限)映射到BSM模型中,利用复利摩尔定律和BSM模型公式计算出IaaS云服务在两种定价方法(pay-per-use和subscription)下相对应的价格范围,并分析了两种定价方法的适应范围,更好地解决了现阶段对于IaaS云服务定价中只有云计算服务提供商单边定价的弊端,并从云计算服务提供商和用户两者的角度提供了对于IaaS服务价格的衡量标准。
Firstly,this paper summarized all of the IaaS cloud service pricing method,and determined the pay-per-use and subscription pricing methods of the cloud services industry generally uses.By analyzing the IaaS service pricing factors,it got the main factor of IaaS cloud computing services:quality of service levels.It mapped five basic parameters of IaaS cloud serv-ices (initial investment,contract period,rate of depreciation,quality of service and age of resources)to BSM model,and used the compounded-Moore’s law and BSMformula to calculate the ranges for pay-per-use and subscription pricing methods. It is better solve the disadvantages of computing service providers pricing for IaaS computing service,and provides the meas-ures for cloud computing service from cloud computing service providers and IaaS cloud service users.
