Cloud Computing is known as a new IT resources delivering business model. The new service which can attract customers is largely dependent on its price. How do the Cloud Service Providers price their services prices? This paper targets three cloud service samplings such as Google, Amazon and Microsoft to collect data. It is found that the prices is not only determined by the service itself but also determined by the pricing models. In another words, different pricing model, different price in the same service. The two pricing models are the pay-per-use pricing model and the subscription pricing model. Pricing models for different cloud services have taken one of four forms: tiered pricing, per -unit pricing, subscription-based pricing, and dynamic pricing. The paper identifies which forms do the cloud service models(IaaS, PaaS and SaaS) take respectively.
