摘要
结合云计算的特点,在分析计算资源的效用市场基础上,从经济学原理的角度提出了云计算经济学架构,设计了基于SLA的云资源管理经济模型。研究了该模型采用的基于使用量的计费机制、基于SLA的谈判流程、基于效用函数的谈判算法,采用CloudSim模拟工具进行仿真实验和性能分析,实验结果表明,该模型有助于促进云环境下资源的高效管理、优化配置,最大限度地满足用户QoS需求。
By analyzing the utility market of computing resources, a cloud computing economic architecture and a cloud resources economic management model based on SLA are proposed. Then, the billing mechanism by usage, the negotiation process by SLA, and the negotiation algorithm by utility function are illuminated in detail. Finally, simulation experiments and performance analysis are done by CloudSim simulation tool. It proves that the model can advance the efficiency of resource management, optimize the configuration in cloud environment, and meet the QoS requirement of users.
