In one embodiment, a cloud computing system provides user extensibility by providing a plugin interface for major systems. Plugin interfaces for a compute service, object service, network service, authentication and authorization service, message service, and image service are disclosed. One or more of the plugin interfaces can be used to alter the allocation of virtual to physical resources across multiple services. Compound services and smart allocation facilities are possible with user-directed modification.

Pluggable allocation in a cloud computing system

A virtual machine management system is used to instantiate, wake, move, sleep, and destroy individual operating environments in a cloud or cluster. In various embodiments, there is a method and system for transferring an operating environment from a first host to a second host. The first host contains an active environment, with a disk and memory. The disk is snapshotted while the operating environment on the first host is still live, and the snapshot is transferred to the second host. After the initial snapshot is transferred, a differential update using rsync or a similar mechanism can be used to transfer just the changes from the snapshot from the first to the second host. In a further embodiment, the contents of the memory are also transferred. This memory can be transferred as a snapshot after pausing the active environment, or by synchronizing the memory spaces between the two hosts.

Method and system for transferring a virtual machine

Several different embodiments of a flexible virtual machine management system are described. The virtual machine management system is used to instantiate, wake, move, sleep, and destroy individual operating environments in a cloud or cluster. In various embodiments, the virtual machine management system uses single messages to perform complex operations, allowing for flexible and scalable use of virtual resources in a cluster while still reducing energy consumption to the minimum possible level. In one preferred embodiment, Wake-on-LAN packets are used as the messages.

Wake-on-LAN and instantiate-on-LAN in a cloud computing system

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.

Multi-level cloud computing system

A cloud computing system including a computing device configured to run virtual machine instances is disclosed. The computing device includes a hypervisor program for managing the virtual machine instances. A customer virtual machine instance is run by the hypervisor program on the computing device, and a grid virtual machine instance is run by the hypervisor program on the computing device. The grid virtual machine instance is configured to run only when a resource of the computing device is not being utilized by the customer virtual machine instance.
