Administration of load balancing software in servers of a virtual private network to update load balancing information

摘要

An administrative manager is connected to servers of a server pool each of which has a host OS including a software load balancer and a guest OS executing a service program in a virtual machine environment. The server in which the guest OS for executing the service program being the source of a processing request to be load balanced is set as a setting objective server of the software load balancer. Further, the server in which the guest OS for executing the service program being the target of the processing request is set as a load balancing objective server. An instruction is transmitted to the setting objective server to load the software load balancer in the host OS thereof, and, an instruction is transmitted to the setting objective server to set information to be used for the load balancing of transmission of requests.
