The present invention provides an information processing device that outputs a machine disposition plan for moving virtual machines while suppressing deterioration in user experience performance in a virtual-machine-type thin client system. The information processing device is provided with: a connection time determination unit that, for each first virtual machine, calculates a time slot coverage rate that is the fraction of a connection time slot covered by a high-load time slot, and determines as a second virtual machine a first virtual machine of which the time slot coverage rate exceeds a minimum coverage rate; and a disposition plan generating unit that, on the basis of time-series data of the amount of resource use of each second virtual machine, calculates the number of physical servers necessary to hold the second virtual machines in each of the high-load time slot and a low-load time slot, and associates the number to the virtual machines, outputting the result.

Virtual machine resource allocation based on connection time coverage exceeding a minimum threshold

A system utilization rate managing device that realizes a management of a system performance and an optimization of the number of operating nodes of different performances and architectures is provided. A node maximum-performance setter of a processing device files a maximum performance of each node constituting an external system into a node maximum-performance memory section of a memory device. A resource utilization rate acquirer acquires a resource utilization rate of each node, and gives it to a virtual utilization rate calculation section. The virtual utilization rate calculation section calculates a virtual utilization rate of the system from the maximum performance of each node retained in a node maximum-performance memory section and the resource utilization rate of each node, and gives the virtual utilization rate to an output section. The output section outputs the virtual utilization rate to an output device.

System utilization rate managing apparatus and system utilization rate managing method to be employed for it, and its program

Disclosed is a billing system that charges resource users for the utilization of a shared resource. The billing system acquires data representing a resource utilization rate at intervals, calculates a utilization rate difference between the acquired resource utilization rate and a reference (average) resource utilization rate, and substitutes the utilization rate difference for the argument of a predetermined math function, such as linear function, to produce a collective adjustment payment (surcharge or discount). Individual adjustment payments are obtained from the collective adjustment payment respectively for resource users.

Billing system and method for charging users for utilization of shared resource

A server migration planning system for planning server migration from source servers to destination servers is provided. A processor allocates the respective source servers to any ones of the destination servers, based on the resource usage of the respective source servers and resource capacity of the respective destination servers. The processor selects the source servers one-by-one in descending order of the resource usage, selects any one of the destination servers, and makes a comparison between a comparison-object usage as the resource usage of the selected source server and a remaining amount of the resource capacity of the selected destination server. If the comparison-object usage is more than the remaining amount, the processor selects another destination server and then makes the comparison again. If the comparison-object usage is not more than the remaining amount, the processor allocates the selected source server to the selected destination server.
