1. A computer implemented system including at least one computer processor for executing a 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 executed in a service delivery platform according to a new Telecommunication Information Networking Architecture (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; physical resources of the TINA-variation architecture include 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-projects' and online-projects' 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 projects' point-of-delivery; the Project Logical Environment Storage Network includes multiple sets of offline-project instances' point-of-delivery; the Project Logical Environment Resource Network includes multiple sets of online-project instances' 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 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; wherein the Access Session Layer includes access session related components: an Access Session Developer-Operator, an Access Session Application User, two Provider Agents, two Initial Agents, a Developer-Operator Agent, a User Agent, and a Subscription Management Component; wherein the Access Session Developer-Operator is used to create a new session in which the project developer plans a logical point-of-delivery, while the developer obtains the project-specific resource requirements; the project operator schedules the activate time, the moment when the project's logical point-of-delivery maps to physical point-of-delivery; the Access Session Application User by which user joins a session, finds the point-of-delivery, and then the user can use the resources; the Two Provider Agent help project developer, project operator or application user to establish trust relationships among them; send a project-developer request to the Developer-Operator Agent to establish new session; or receive an invitation from the User Agent for application user; wherein each access session creation will generate a Provider Agent instance; the Two Initial Agent are independent of project developer, project operator, and application user; the two initial agent are the initial access points in a Resource Provision Domain; When project developer, project operator or application user try to contact or create session with Resource Provision Domain, Initial Agent will reply a message to Provider Agent; By interacting with Provider Agent, Initial Agent supports identity authentication and trust relationship establishment between project developer/project operator/application user and Resource Provision Domain; the Developer-Operator Agent is on behalf of project developer or project operator in the Resource Provision Domain, and acts as a single contact point in access session, to control and manage new project's Operator Service Session Manager, contact information between the project developer or project operator and the Resource Provision Domain can be obtained from the Developer-Operator Agent as well; the User Agent is on behalf of application user in the Resource Provision Domain, and acts as a single contact point in access session to control and manage a new User Service Session Manager; contact information between the application user and the Resource Provision Domain can be obtained from the User Agent as well; the Subscription Management Component provides the management function of subscription-service information model in the Resource Provision Domain.
