摘要: A service appliance is installed between a production server running a service applications and service users. Upon being connected with the production server, the service appliance contacts the production server and/or service application and automatically replicates the service data from the service application. As additional service data is added to or modified by the service application of the production server, the service appliance automatically updates its replica of the data. In the event that a production server is unable to provide its service to users, the service appliance can transparently intervene to maintain service availibility using the replica of the data. When an operational production server is connected with the service appliance, the service appliance can automatically copy its service data to the service application of the operational production server. The operational production server can be the same as the original production server or a new production server.
