Abstract: Network presence of a computing device in a cloud computing network is maintained while power consumption of the computing device is reduced. When the computing device is determined to enter an idle state, at least some of the operations of the computing device running in a virtual machine environment are migrated to a server within the cloud computing network while maintaining connectivity of the computing device to the cloud computing network. When the computing device is determined to be in the idle state, the computing device is put into a sleep mode to reduce power consumption of the computing device. When the computing device is determined to be in an active state, the computing device is woken, and the migrated operations are returned from the server to the computing device. This reduces power consumption of the computing device while maintaining the network presence of the computing device in the cloud computing network.

Abstract: A method and a system for creating a network of virtual machines in a communication network including a head node virtual machine (VM) for distribution and processing of a workload. The method comprises creating the head node VM hosted at a server computer, the head node VM specifying the workload, the workload being assignable into sub-tasks; identifying a pool of hosts for hosting a plurality of replica VMs, each of the pool of hosts comprising a physical computing device; replicating the head node VM at an each one of the plurality of replica VMs; coordinating amongst the plurality of replica VMs to assign at least one workload sub-task to the each one of the plurality of replica VMs; processing the at least one assigned workload sub-tasks at the respective each one of the plurality of replica VMs to provide at least one sub-task result; and receiving the at least one sub-task result at the head node VM.
