云计算的经济学最近引起了越来越多的关注。特别是，仍在争论的一个话题是如何向客户收取云资源的价格，因为可以考虑替代定价规则。基于受全球主要云服务提供商 Amazon EC2 使用的定价方案启发，我们在本文中解决了两个主要问题。首先，我们提出了一种以最佳方式确定定价规则相关参数的方法，即最大化提供商的收入。此外，我们还讨论了访问云时同时存在三种定价规则（而不是更少）的原因。我们的研究结果表明，这可能是由于潜在需求的覆盖面更大，因为申请云服务的客户在支付工作费用的意愿、服务的时间长度、所需的计算能力等方面存在差异。此外，所谓现货市场的定价规则可以为平台提供有关客户支付云服务意愿的有用信息。这是因为在现货市场上，用户提供服务价格，但如果他们的请求得到满足，则支付的价格会低于该价格。
The economics of cloud computing has recently attracted increasing attention. In particular, a topic which is still under debate is how prices charged to customers for cloud resources are formed, since alternative pricing rules could be considered. Based on three pricing schemes inspired by those used by Amazon EC2, the main global cloud service provider, in the paper we address two main issues. First we present a methodology for the relevant parameters of the pricing rules to be determined in an optimal way, that is to maximise the provider's revenue. Moreover, we discuss reasons for co-existence of three pricing rules, rather than fewer, to access the cloud. Our findings suggest that this may be due to a larger coverage of the potential demand, since customers applying for cloud services vary in their willingness to pay for the job, the time length of the service, the computational power requested etc. Furthermore, the pricing rule in the so-called, spot market, can provide the platform with useful information on the customers willingness to pay for cloud services. This is because in the spot market users offer a price for service, but pay less than that if their request is satisfied.
