Abstract:
The present invention relates to a method for provisioning virtual machines (VMs) based on a space vector transformation scheme and, more specifically, to a method for provisioning virtual computing resources (virtual machines) as a virtualization or cloud computing resource management technology. The present invention expresses a necessary work load and resource of the VM in a vector form and applies a rapid and immediate VM arrangement algorithm, thereby bringing a big enhancement in terms of processing speed as compared with a traditional method.
Abstract:
PURPOSE: A device and a method for managing contents of a cloud gateway are provided to minimize a request-and-respond time when requesting a contents reading, and to satisfy a cloud storage selection policy of a user through a home cloud gateway server within a home connected with a heterogeneous cloud infra. CONSTITUTION: A cloud service system comprises at least one user device, multiple clouds providing heterogeneous cloud services, and a gateway connected between the user device and the clouds. Information tables (222,223) of the gateway store predetermined service level agreements. A controller (225) of the gateway selects more than at least one cloud among the clouds according to service level agreement information, and stores contents provided from the user device in a selected cloud. [Reference numerals] (211) Hash table; (222) Information table for service level agreements (SLA); (223) Information table for response time (RT) per content request; (224) Content multi-copy generator; (225) Multi-copy storing controller; (226) Response time calculator; (227) Multi-copy selector; (AA) Home cloud gateway
