基于浮动利率的PaaS平台计费模型研究

The billing for PaaS platform is studied. In consideration of the fact that the cluster resource benefit of the traditional PaaS billing model is low because its billing strategy neglects the resource utilization, a new billing model based on surge rate is proposed through improving the billing method based on the actual amount used. The surge rate is related to the actual resource utilization of transaction and constrained by the platform resource cost and user utility, so it guarantees to improve the benefit of unit resource by calculating the dynamic rate based on actual usage. The experimental results show that the proposed billing model could optimize platform’s resource utilization from the perspectives of supply and demand, and improve the benefit of platform resources under the premise of guaranteeing the profit.
