Server allocation control method
WO 2004092971 A1
Allocation of the servers in a data center to network services is automatically conducted by a load distributing device on real time without any manual operation. The variation in the quantity of requests arriving at each network service is monitored, the value of the quantity of requests after a predetermined elapsed time is predicted. Depending on the magnitude of the request quantity predicted value, the allocation quantity of servers to the network service can be controlled. The quantity of servers allocated to the network service is so determined that the average of response times to user terminals is a response time threshold or less predetermined by the operation manager when a traffic of a quantity indicated by the request quantity predicted value arrives at the network service. The server group can include a requisite minimum number of servers necessary for the operation of the network services so that it is judged whether or not the response times based on the predicted value are in a predetermined range each time the a server is added or eliminated.
