On-demand service in grid: architecture, design and implementation

Service oriented architecture becomes the mainstream of grid research today. On-demand service, which can provides better flexibility for grid users, is purposed in this paper. According to the research on different implementation policies, on-demand service architectures for virtual machine based on-demand service and service specification reference based on-demand service is proposed. Furthermore, it is designed and implemented based on Java virtual machine and Groovy script language. Performance testing to the implementation shows that on-demand service can provide better flexibility for grid by low cost, and can speedup mass data processing services usually.
