Claim 9:
10. A management device that manages a usage configuration of a service provided between first devices of a first device group and second devices of a second device group, the management device comprising:
a processor that executes a program; and
a storage device that stores the program,
wherein the storage device has a configuration management table, a cost calculation rule table, and a performance/capacity history table,
wherein the configuration management table stores a first storage region of the first devices, a second storage region of the second devices, and a type of the usage configuration,
wherein the performance/capacity history table stores an observation item in the first storage region, an observation value pertaining to the observation item, and an acquisition date/time of the observation value,
wherein the cost calculation rule table stores one or more cost calculation formulas that serve as rules for calculating a cost for use of the second storage region according to the type of the usage configuration on the basis of at least one of the first storage region, the observation value, and the acquisition date/time, and
wherein the processor executes:
an acquisition process of acquiring configuration management information including at least the first storage region and the second storage region;
an extraction process of extracting, from the cost calculation rule table, the cost calculation formula in the second storage region included in the configuration management information acquired in the acquisition process;
a first calculation process of calculating a cost estimate value by the cost calculation formula by acquiring, from the performance/capacity history table, a value to be substituted in as a variable of the cost calculation formula;
a creation process of creating a cost estimate result including a cost estimate value calculated in the first calculation process, the first storage region, the second storage region, and the type of the usage configuration using the second storage region; and
an output process of outputting the cost estimate result created in the creation process.
