Multi-level cloud computing system

Abstract

A cloud computing system includes a physical resource pool that includes a number of information processing devices. Each information processing device includes a processor, a computer-readable medium, and a network interface. The system further includes a first cloud controller to manage a first cloud infrastructure, the first cloud infrastructure operating a first set of virtualized resources, the first set of virtualized resources having access to the physical resource pool through the first cloud controller. The system further includes a second cloud controller to manage a second cloud infrastructure, the second cloud infrastructure utilizing the first set of virtual resources to operate a second set of virtual resources, the second set of virtual resources being provided access to the physical resource pool through the second cloud controller and the first cloud controller.

What is claimed is: 
     
         1 . A cloud computing system comprising:
 a physical resource pool comprising a number of information processing devices, each information processing device comprising a processor, a computer-readable medium, and a network interface;   a first cloud controller to manage a first cloud infrastructure, the first cloud infrastructure operating a first set of virtualized resources, the first set of virtualized resources having access to the physical resource pool through the first cloud controller; and   a second cloud controller to manage a second cloud infrastructure, the second cloud infrastructure utilizing the first set of virtual resources to operate a second set of virtual resources, the second set of virtual resources being provided access to the physical resource pool through the second cloud controller and the first cloud controller.
