Further research on market oriented grid based on contract management

Recently the rapid development of information technologies has caused that computing resources including computational power, memory storage, network bandwidth, devices and instruments are commoditized and delivered in a manner similar to traditional utilities. Grid Market and Cloud Computing are focused on to approach this utility computing vision. A Market Oriented Grid Model (MOGM) based on contract management is further researched in this paper. Firstly, the differences between Cloud Computing and MOGM are discussed. Secondly, a new reputation evaluation model is proposed and applied into MOGM. Thirdly, a solution integrated with payment management and reputation management is discussed based on contract management mechanism. The simulation results reveal that the market can be kept in healthy operation.
