Claim 6:
7. A method for operating a scalable interactive voice response (IVR) system, the IVR system comprising a plurality of IVR servers and a load balancer, the method comprising:
monitoring, by the load balancer, a number of active IVR sessions for one or more IVR servers of the plurality of IVR servers;
analyzing, by the load balancer, a plurality of historical scaling events to predict a future session requirement;
responsive to monitoring the number of active IVR sessions and based on the predicted future session requirement, determining that the number of IVR sessions for one or more IVR servers is less than a session threshold;
generating a scaling down indication for the IVR system, the scaling down indication comprising an identification of a selected server to be removed from the plurality of servers;
responsive to generating the scaling down indication, de-registering the selected server from IVR traffic by the load balancer;
after de-registering the selected server, preventing assignment of an IVR event to the selected server; and
communicating, by the IVR system and to a cloud provider, a request for termination of the selected server.
