  • n servers having m kinds of resources, where m and n are positive integers numbering two or more;

    a resource management server which receives changed amounts of the kinds of resources from each server at predetermined intervals; and

    wherein the load is determined as a ratio of the necessary amount to the useable amount of each kind of resources in each server; and

    wherein the service distributor determines a server having a minimum value of a maximum ratio of the necessary amount to the useable amount of each kind of resources.
