A policy determination apparatus includes an acquisition unit, a metrics generation unit, an evaluation unit, and a policy determination unit. The acquisition unit acquires monitoring data relating to states of facilities on a network. The metrics generation unit generates, based on the monitoring data, time-series data of types of metrics associated with candidates of routing destinations to which a routing control apparatus routes requests. The evaluation unit evaluates the candidates based on the time-series data to generate routing destination evaluation data. The policy determination unit determines, based on the routing destination evaluation data, a policy that the routing control apparatus uses for control of the routing destinations.
