DISASTER TOLERANCE SERVICE SYSTEM AND DISASTER TOLERANCE METHOD

摘要

A disaster tolerance service system and a disaster tolerance method are disclosed. The disaster tolerance service system comprises: a fault detection module (11) for detecting whether a service server operating service and/or the service are in a fault state; a server management module (12) for determining a disaster tolerance server to replace the service server if a detection result is yes; a service load/unload module (13) for loading the service on the disaster tolerance server; a service operation module (14) for operating the service on the disaster tolerance server. This technical solution improves the disaster tolerance reliability and reduces the cost spent on the disaster tolerance service system.
