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) configured to detect whether a service and/or a service server for operating the service are/is in a fault state; a server management module (12) configured to determine a disaster tolerance server for replacing the service server if a detection result is that the service and/or the service server for operating the service are/is in the fault state; a service install/uninstall module (13) configured to install the service on the disaster tolerance server; and a service operation module (14) configured to operate 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.
