An apparatus for estimating a demand for a service offered via a network includes an external-factor storing unit that stores an event for a case in which information relating to the service appears in a predetermined information source on the network, as an external factor affecting the demand; a demand-amount calculating unit that calculates an amount of the demand for the service by determining whether the event as the external factor stored is appeared in the predetermined information source; and a resource-change instructing unit that instructs a change of a resource allocated to the service, according to the amount of the demand calculated.

Method and apparatus for estimating demand, and computer product

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.

In a system that dynamically assigns software to a plurality of servers to perform customer services, an index to which there have been integrated the newness of a customer's software and the security level of the software is calculated, and whether the calculated index satisfies restricting conditions is checked. If the calculated index does not satisfy the restricting conditions, revision information is applied to the software.
