A Computing Resources Market Model and Supply-Demand Matching Mechanism

To facilitate computing resources commercialization and to encourage more users to participate in the trading, we propose a computing resource market model CR-Market in this paper. Compared with existing Grid and Cloud markets, CR-Market has the following distinctive features: (1) Its architecture is based on the combination of Grid and Cloud. Market participants include buyers and sellers of Cloud providers, Cloud users and ordinary Grid users. (2) The transaction prices are floated by the matching mechanism and current supply-demand circumstances. Both sellers and buyers have the same right to affect the deal price. (3) Quality-aware models of supply and demand are used to express different resource qualities of and individual user's quality requirements. (4) Quality-aware matching algorithms based on double auction are designed and studied by simulation in this paper. Compared with traditional double auction, the simulation results reveal that the Quality-aware matching algorithms can not only guide users to rational pricing but also get higher matching success ratios and total transaction amounts.
