The replica creation technology of Grid can not replicate Grid Services which are with state and include software and hardware requirements

while only replicate datum and file resources which are no state.Aiming at resolving the question such as accessing bottleneck

load balance of Grid Service

we advise a replica creation approach of Grid Service with state based on Virtual Workshop called Ragsres.Ragsres implements the replication of software and hardware environment using customized trait and well executing separation attribute of Virtual Workshop.It accomplishes the replication of Grid service memory state based the snapshot of Virtual Machine Monitor.The approach realizes the replication of resources with state

which adopting modeling technology of Web service.
