SYSTEMS AND METHODS FOR DYNAMICALLY EXPANDING LOAD BALANCING POOL

摘要

The present application is directed towards systems and methods for configuring and applying autoscaling to a service group of an intermediary device for a domain based server. All the IP addresses resolved by the domain name of the server and that are determined as up will automatically become members of the service group. The resolver monitor will resolve the server's domain name based on the TTL (Time to Live) value in the address record or whenever the appropriate command is executed. Each time the domain is resolved, if there is a change in the number of IP addresses resolved, then the members of the service group will shrink or expand based on the number of IP addresses resolved

1. A method comprising:
establishing, by a device intermediary to a plurality of clients and a domain based server for a domain name, a service group associated with the domain based server, the service group configured to automatically scale members of the service group based on resolving internet protocol (IP) addresses for the domain based server; resolving, by the device, the domain name into a plurality of IP addresses; determining, by the device, a status of each of the IP addresses for the domain name; changing, by the device, members of the service group based on the status of each of the IP addresses for the domain name; and load balancing, by the device, a plurality of client requests to the domain based server across the changed members of the service group.
