Recently grid computing has started to leverage Web services technology by proposing OGSI-standard. OGSI standard defines the grid service, which presents unified interfaces to every participant of grid. In current Glubus Toolkit3(GT3),which is an implementation of OGSI, grid service factories should be deployed manually into resources to provide grid services. However, it is necessary to dynamically allocate proper amount of resource, since the demand for resource of service provider changes over time. In this paper, we propose a architecture to enable on-demand resource provisioning. We develop universal factory service (UFS) that provides a dynamic grid service deployment mechanism and a resource broker called door service. Through the experiments, we show that grid services can adaptively exploit resources according to the request rates.
