混合云市场的计算资源交易模型

摘要

A computing resource trading model named HCRM(Hybrid Cloud Resource Market)is proposed based on hybrid cloud environment. The market structure, management layers and quality models of supply and demand are dis-cussed. A quality-aware double auction algorithm named QaDA(Quality-aware Double Auction)is designed and simulated. Compared with traditional CDA(Continuous Double Auction), the simulation results show that QaDA not only can guide reasonable price but also can obtain higher matching ratio and higher deal amount.%基于计算资源共享模型的研究，提出了混合云计算资源市场HCRM（Hybrid Cloud Resource Market）的功能架构，研究了市场管理层的交易管理机制，给出了计算资源的供需质量模型，设计了一种质量感知的双向拍卖算法QaDA（Quality-aware Double Auction）。仿真运行结果表明，与普通的连续双向拍卖算法CDA（Continuous Double Auction）相比，QaDA不仅可以引导用户合理定价，也能获得较高的匹配成功率和较高的交易总额。
