摘要： A service appliance is installed between production servers running service applications and service users. The production servers and their service applications provide services to the service users. In the event that a production server is unable to provide its service to users, the service appliance can transparently intervene to maintain service availability. To maintain transparency to service users and service applications, service users are located on a first network and production servers are located on a second network. The service appliance assumes the addresses of the service users on the second network and the addresses of the production servers on the first network. Thus, the service appliance obtains all network traffic sent between the production server and service users. While the service application is operating correctly, the service appliance forwards network traffic between the two networks using various network layers.

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 availability 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.

摘要： A service appliance is installed between production servers running service applications and service users. The production servers and their service applications provide services to the service users. The service appliance replicates the service data of service applications and monitors the service application. If the service appliance detects that the service application has failed or is about to fail, the service appliance takes control of the service. Using the replica of the service data, the service appliance responds to service users in essentially the same manner as a fully operational service application and production server and updates its replica of the service data as needed. When the service appliance detects that the service application has resumed functioning, the service appliance automatically synchronizes the data of the service application of the production server with the service appliance's data and returns control of the service to the service application and its production server.
