    Abstract: The present invention achieves load balancing among physical nodes in a distributed database environment. The information processing system (100) of the present invention includes: a plurality of database servers (122) which are characterized in being a plurality of database servers (122) which are distributed in being deployed upon a plurality of physical nodes (124), wherein among the plurality of database servers (122), two or more servers which are each mutually responsible for different data are deployed upon the same physical node, and one or more servers which are responsible for the same data as any of the two or more servers are each deployed upon one or more other physical nodes; and distribution units (140 and 170), which monitor the loads related to each of the physical nodes, move a connection with a client from a database server upon a physical node which has a load which is larger than a target to a database server upon a physical node which has a load which is smaller than the target in order to distribute the connections so as to balance the loads thereof.
