Abstract
An auto scale monitoring service performs load balancing on a cloud firewall with minimized traffic disruption using eager and lazy load balancing protocols. The auto scale monitoring service operates through an orchestrator that initializes a new firewall and sends forwarding instructions to the new firewall for rerouting excess traffic. The auto scale monitoring service additionally operates through a software-defined wide area network controller that sends routing instructions to a local branch of network devices to reroute to the new firewall from an overloaded current firewall. The eager protocol immediately tears down a tunneling session from the local branch to the current firewall and the lazy protocols gradually tears down this tunneling session. Both protocols properly inform firewalls how to forward ongoing traffic in each case and establish updated traffic flow through a tunneling session from the local branch to the new firewall.
