【摘要】：近年来，随着基础设施即服务（Infrastructure as a service，IaaS）商用化程度的不断加深，其定价方式成为云服务业界和学术界关注的焦点。IaaS与传统的信息产品和服务有着一些共性，，但是由于时代背景、文化传统、IT技术和经济环境变化的影响也具有了自身独特的方面，例如边际成本为零、高可扩展性和弹性服务等。IaaS云计算服务提供商需要制定和运用行之有效的定价策略、定价方法和价格竞争策略，才能扩大自身的市场份额，巩固自身的市场地位，增强自身的竞争能力。而现阶段IaaS云计算服务的定价基本都是采用按需付费这种单一定价模式，因此如何丰富IaaS云计算服务定价策略和方法，并且分析研究IaaS云计算服务价格竞争策略的相关问题是当前云计算研究的热点。本文首先论述了IaaS云计算服务的概念、特点及发展现状，并分析论述了云计算的相关基础理论，随后着重研究了IaaS云服务的定价策略、定价方法、定价区间和价格策略。具体而言，主要研究内容如下：（1）IaaS云计算服务定价影响因素、定价策略和定价方法。基于对亚马逊和微软两家云服务企业IaaS云服务计费模式的研究，提出了来自于云服务提供商和用户两方面的定价影响因素；接着得出云服务提供商采用的时间材料定价策略、两阶段定价策略、差异化定价策略和拍卖式定价策略四种定价策略；最后将四种定价策略进行抽象，得出了云服务市场上普遍采用的Pay-per-use、Subscription和动态定价方法三种定价方法。（2）基于BSM模型的IaaS云计算服务价格范围度量。在对IaaS云服务资源参数划分的基础上，把资源参数映射到BSM模型中，计算得出Pay-per-use和Subscription两种定价方法下不同云服务质量水平的价格范围，比较分析了在一年期（短期）和三年期（长期）两种定价方法下云计算服务提供商所获得的收益情况，为提供商制定IaaS云计算服务价格提供方法指导。（3）IaaS云计算服务价格竞争问题研究。基于对IaaS云计算服务质量水平的划分，提出了云服务提供商提供的两种服务质量水平的云服务--标准质量服务水平和高质量服务水平。然后从云服务提供商收益的角度出发，分析研究了短期性和长期性IaaS云计算服务条件下两家云服务提供商提供不同云服务质量水平的价格竞争策略问题。
[Abstract]:In recent years, with the deepening of the commercialization of (Infrastructure as a service,IaaS (Infrastructure as a Service), its pricing method has become the focus of the cloud service industry and academia. IaaS and traditional information products and services have some similarities, but due to the background of the times, Cultural tradition, the influence of IT technology and economic environment change also has its own unique aspects, such as zero marginal cost, high scalability and flexible services, etc. IaaS cloud computing service providers need to develop and use effective pricing strategies. Only by pricing method and price competition strategy can we enlarge our own market share, consolidate our market position and enhance our own competitive power. At this stage, the pricing of IaaS cloud computing services is basically based on the ondemand pricing model, so how to enrich the pricing strategies and methods of IaaS cloud computing services, And the research of IaaS cloud computing service price competition strategy is the focus of cloud computing research. This paper firstly discusses the concept, characteristics and current situation of IaaS cloud computing service, and analyzes the basic theory of cloud computing. Then, it focuses on the pricing strategy, pricing method, pricing interval and price strategy of IaaS cloud service. Specifically, the main contents are as follows: (1) IaaS cloud computing services pricing factors, pricing strategies and pricing methods. Based on the research of IaaS cloud service billing model of Amazon and Microsoft, this paper puts forward the pricing influence factors from cloud service provider and user, and then obtains the time material pricing strategy adopted by cloud service provider. Two stage pricing strategy, differential pricing strategy and auction pricing strategy are four pricing strategies. Finally, the four pricing strategies are abstracted. Three pricing methods, Pay-per-use,Subscription and dynamic pricing, which are widely used in cloud service market are obtained. (2) IaaS cloud computing service price range measurement based on BSM model. Based on the partition of IaaS cloud service resource parameters, the resource parameters are mapped to the BSM model, and the price range of different cloud service quality levels under two pricing methods, Pay-per-use and Subscription, is calculated. A comparative analysis of the benefits received by cloud computing service providers under two pricing methods, one year (short term) and three year (long term), It provides guidance for providers to develop IaaS cloud computing service price. (3) Research on price competition of IaaS cloud computing service. Based on the classification of IaaS cloud service quality level, two kinds of cloud services of cloud service provider, standard quality service level and high quality service level, are put forward. Then, from the point of view of cloud service provider's income, this paper analyzes and studies the price competition strategy of two cloud service providers under the condition of short-term and long-term IaaS cloud computing service with different cloud service quality level.
