Provisioning manager for optimizing selection of available resources

A method and software for fulfilling a resource request in a data processing network includes specifying characteristics of the requested resource responsive to detecting the resource request. A set of attributes is then derived from the specified characteristics. The specified characteristics indicate broad or general properties of the needed resource while the derived attributes preferably indicate the hardware and software components of a resource ideally suited to fulfill the resource request. Attribute information associated an available resource is then evaluated against the attributes derived from the specified characteristics. An available resource is then selected, based on the evaluation, to satisfy the resource request. The attributes of the selected resource best match the attributes derived from the specified characteristics. The requested resource may be a server resource and specifying the characteristics of the requested resource may includes specifying a server type from a constrained set of server types.
