Abstract: Server management data describes observed operating condition of a pool of spare servers. Based on a demand forecast of a specific target system, a dynamic allocation period is determined as a period during which the target system needs additional server resources to handle an expected demand. Based on the dynamic allocation period and server management data, a set of allocation candidates are nominated from the spare server pool, by eliminating therefrom spare servers which are likely to fail during the dynamic allocation period. An appropriate allocation candidate is then selected for allocation to the target system, such that the selected candidate will satisfy a specified requirement during its allocation period.

Abstract: A record medium on which a load distribution program capable of dynamically determining a service providing server which can provide a service of high quality according to a place where a client is installed is recorded. A delay time determination section analyzes a request sent from a client, identifies a position on a network of the client, and determines processing delay time the client takes to receive a response from each data center on the basis of a communication path between the position of the client and a position on the network of each data center. An allocation determination section preferentially selects a data center which can provide a service to the client after shortest processing delay time as a recommended data center on the basis of the processing delay time determined by the delay time determination section. A service allocation section makes a server in the recommended data center provide the service to the client which outputted the request.

Abstract: A relay control apparatus is arranged between clients and a CoD system. The relay control apparatus accepts process requests from the clients and stores the process requests. If the CoD system is installing a server in addition to existing servers, the relay control apparatus provides a control so that requests unprocessable with the existing servers are not passed to the CoD system until the installation of the server is completed. When the installation of the server is completed, servers that can process, within a predetermined period, a volume of requests at that time and a volume of requests retained by that time are secured.
