1. A computer software mapping system of mapping logical point-of-delivery to physical point-of-delivery for cloud computing resource management in enterprise data center, wherein the mapping system is realized in a service delivery platform and the mapping system is implemented with a new TINA-variation architecture; a service target of the TINA-variation architecture is an enterprise data center; the TINA-variation architecture includes an Access Session Layer, a Service Session Layer, a Resource Session Layer, and a Provision Session Layer; the TINA-variation architecture is left-right asymmetrical; resources of the TINA-variation architecture includes IT resources, storage resources, and network resources; the service delivery platform is used by a project developer, a project operator, an application user, and a system operator; wherein the service delivery platform includes a Project Delivery Service Network, a Project Logical Environment Service Network, a Project Logical Environment Storage Network, a Project Logical Environment Resource Network, a Virtual Resource Network, and a Data Center Physical Resource Service Network Divided by Project; the Project Delivery Service Network includes a Project Core Service, a Project Design Service, a Project Delivery Scheduling, and a Project Subscription Service; the Project Logical Environment Service Network includes multiple sets of offline-project's and online-project's logical point-of-delivery, in which the project-delivery-and-scheduling function supports automatic or manual offline-online environment switching, and supports scheduling multiple sets of project's point-of-delivery; the Project Logical Environment Storage Network includes multiple sets of offline-project instance's point-of-delivery; the Project Logical Environment Resource Network includes multiple sets of online-project instance's point-of-delivery; the Virtual Resource Network in which virtual resources aggregate physical resources of different configurations and different locations, is configured to achieve resource consolidation regardless of type and deployment of the physical resources; wherein the virtual resource network includes unallocated and allocated virtual resources and the Virtual Resource Network provides support of exclusive holding or sharing virtual resources; the Data Center Physical Resource Service Network Divided by Project includes multiple sets of physical point-of-delivery; the Data Center Physical Resource Service Network Divided by Project supports subscription and commitment (i.e., delivery) of the point-of-delivery, and supports sharing physical resources by space or by time; and the Data Center Physical Resource Service Network Divided by Project includes unallocated and allocated physical resources.
