Research on QoS Optimization Method of Cloud Service Based on Utility Game between Users and Service Providers in the Cloud Market

摘要: Cloud computing brings a rapid way for enterprises to launch new software, which needs lower cost compared with self-purchased infrastructure. More and more compact their business software as services into cloud platform the users. In service auction, provider aims make profits from it provides, but consumer hopes select good quality of at low price, relationship them become one kind game. this paper, game between providers consumers is analyzed. The utility functions are respectively established. Then QoS optimization algorithm based on designed solve an optimal strategies achieve tradeoff satisfaction profit. Finally simulation experiments implemented by using Matlab platform. experimental results show that can effectively optimize two aspects preference cost, bring largest improvement user lowest cost. So helps realize win-win situation consumers.
