Claim 0:
1. A method comprising:
receiving, at a controller of a cloud-delivered virtual private network (VPN) system, historical usage data associated with a flow through the cloud-delivered VPN system;
determining, by the controller based at least in part on the historical usage data, that a predicted usage associated with the flow during a period of time exceeds a threshold usage;
determining, by the controller and based at least in part on the predicted usage exceeding the threshold usage, to upgrade the flow during the period of time from a first traffic class to a second traffic class, the second traffic class having greater network performance than the first traffic class;
identifying, by the controller, a data-plane node of the cloud-delivered VPN system that is associated with the second traffic class, the data-plane node having available resources during the period of time to process data-plane traffic of the flow, the data-plane node distinguishable from a control-plane node of the cloud-delivered VPN system for processing control-plane traffic of the flow; and
causing, by the controller, a load balancer associated with the cloud-delivered VPN system to send, during the period of time, the data-plane traffic of the flow to the data-plane node for processing.
