System and method for supporting transaction and parallel services across multiple domains based on service level agreenments

摘要: An on-demand manager provides an improved distributed data processing system for facilitating dynamic allocation of computing resources among multiple domains based on a current workload and service level agreements. Based agreement, the monitors predicts load system. If or predicted cannot be handled with configuration, determines additional needed to handle workload. agreement violations by reconfiguring at domain, sends resource request other domains. These analyze their own commitments may accept request, reject counter-propose offer corresponding agreement. Once requesting domain has acquired resources, balancers are reconfigured allocate some from site remote resources.
