ABSTRACT:
Dynamically upsizing and/or downsizing a network farm in response to network demand. An application message router routes messages to the network farm. When the network farm approaches or is anticipated to be approaching capacity, a group of one or more servers may be added to the network farm. When the added server(s) are capable of participating in the network farm, the application message router is triggered to route also to the added servers. When the network farm has excess capacity, a group of one or more servers may be dropped from the network farm. This may be accomplished by triggering the application message router to no longer route messages to the removed servers. The removed servers may be either immediately or gracefully removed from service.
