Abstract: Disclosed is a method and a device for optimizing load balancing based on cloud monitoring that relate to loading balancing and that can improve the primary/backup Availability Zone (AZ) switchover efficiency of an load balancing instance by intelligently switching the preferences of load balancing devices. The method includes: obtaining statistics on traffic distribution within a controlled area of a load balancing system, statistics on backend servers within a plurality of AZs of the load balancing system, and monitored network quality of the AZs; determining an AZ suitable to serve as a corresponding primary AZ of a load balancing instance based on the traffic distribution statistics, the backend server statistics, and the monitored network quality; and performing a primary AZ switchover of the load balancing instance based on the determined result. The present application is intended for the optimizing of load balancing.

Abstract: Disclosed are a method and a system for forwarding data, as well as a virtual load balancer and a readable storage medium. The method for forwarding data includes: sending the pending response data packet to the real server RS through a rear terminal sub interface, when the virtual load balancer VLB receives a pending response data packet sent by the Linux virtual server LVS from a front terminal sub interface, wherein the forward network port of the VLB corresponds to at least one front terminal sub interface, and a front terminal sub interface corresponds to a carrier's data interface; and the RS receives and responds to the pending response data packet, getting a response data packet and sending the response data packet to the VLB from the rear terminal sub interface; and the VLB receives the response data packet.
