 For example, if the Keyword Forecast provider is being used heavily in the server farm and the providers running on machine "A" are used lightly, the server will automatically deploy the Keyword Forecast provider to machine "A" and route requests to that machine to balance the load for the Keyword Forecast provider.When a client application calls a service provider or stored procedure through the server, a KSP server with a matching service provider or stored procedure is selected by the load balancer provider, and the request is routed to the appropriate KSP server.If a server, service provider, or stored procedure in the KSP server farm is unavailable, it will be taken out of rotation by the load balancer automatically.
