Abstract

A system and method for allowing use of an overflow resource on a temporary basis to supplement a standard resource that is engaged, and thus allows the system to satisfy a resource access request that would otherwise go unresponsed. The system monitors usage of the standard resource to determine if the standard resource is engaged when the request materializes, and then authorizes use of the overflow resource when the standard resource is engaged. The system then activates the overflow resource, whereby the overflow resource responds to the access request. The system then disables the overflow resource when the request is satisfied or when the standard resource becomes available. The system monitors the use of the overflow resource and when the use exceed a predetermined amount of allowed use, either allocates additional overflow resources or licenses the overflow resource, essentially converting the overflow resource to a standard resource.
