Abstract
One aspect of the present invention provides a system for failover comprising at least one client selectively connectable to one of at least two interconnected server via a network connection. In a normal state, one of the servers is designated a primary server when connected to the client and a remainder of the servers are designated as backup servers when not connected to the client. The at least one client is configured to send messages to the primary server. The servers are configured to process the messages using at least one service that is identical in each of the servers. The services are unaware of whether a server respective to the service is operating as the primary server or the backup server. The servers are further configured to maintain a library, or the like, that indicates whether a server is the primary server or a server is the backup server. The services within each server are to make external calls via its respective library. The library in the primary server is configured to complete the external calls and return results of the external calls to the service in the primary server and to forward results of the external calls to the service in the backup server. …
