Abstract:
1. A method for dynamically upsizing a network farm of one or more servers with at least one additional server in response to network demand, the method comprising: initially routing incoming application messages to an initial set of one or more server(s) using an application message router that uses configurable routing settings; identifying a routing policy for the network farm; statistically tracking information corresponding to the initially routed application messages; determining from the tracked information that the one or more servers are reaching capacity; in response to determining that the one or more servers are reaching capacity, modifying the configurable intra-farm routing settings such that subsequent incoming messages are routed to a subsequent set of servers comprising the initial set of server(s) and the additional server, wherein modifying the configurable routing settings is performed using an application program interface that provides a first interface that permits for immediate rerouting of incoming messages away from one or more servers of the network farm that are not in the diminished set and provides a second interface that permits rerouting of incoming messages with at least temporary continuance of routing of incoming messages that correspond to pre-existing stateful sessions to their pre-existing servers even if those pre-existing servers are no longer in the diminished set of server(s).
