A resource lending control apparatus stores an assignment time and a deletion time in association with each other for each customer. The assignment time indicates a time for assigning an application used by each customer to provide a service to a server. The deletion time indicates a time for deleting the application from the server. The resource lending control apparatus calculates a lendable period of a remaining fixed resource of a lending customer by subtracting the deletion time and the assignment time of the lending customer from a remaining fixed period. The resource lending control apparatus calculates a total borrowing period, i.e., a period during which a borrowing customer is to use a borrowed resource, by adding the deletion time and the assignment time of the borrowing customer to a borrowing request period. Then, the resource lending control apparatus determines whether the calculated total borrowing period is covered by the calculated lendable period to determine to lend the remaining fixed resource.
