Methods and apparatuses for managing a service system virtually built are provided. A management server assigns identifiers that are unique to a service system to components used to build the service system, and records connections of the components and the time of building the service system. When detecting a change in the connections of the components, the management server records the changed connection and the time of the change, collects monitoring information and monitoring times from a data center, and records the monitoring information associated with the monitoring times. When receiving information designating a time from a terminal, the management server identifies and outputs the configuration of the service system and the monitoring information at the designated time based on the identifiers of the components associated with the designated time.
