Problems solved by technology

However, when a server crashes, its access traffic will enter the server of the next node, causing the server of the next node to crash due to excessive load, and then the traffic of the two crashed servers will enter the next node together, causing a chain reaction , causing all servers to crash

Abstract

The invention discloses a load balancing method, system and device and a storage medium, and relates to the Internet technology, and the method comprises the following steps: calling a hash function according to a user identifier and a user address to calculate a hash value corresponding to an access request; searching a virtual node with the closest hash value in a pre-established hash ring in a clockwise or anticlockwise direction according to the hash value to obtain a target virtual node, wherein the hash ring comprises a plurality of virtual nodes, each virtual node corresponds to one server node, the number of the server nodes is multiple, each server node corresponds to a plurality of virtual nodes, and the plurality of virtual nodes are randomly distributed on the hash ring; and returning the access address of the server node corresponding to the target virtual node to the client. According to the scheme, load balancing can be realized, and the possibility of an avalanche effect is reduced.

Description

technical field [0001] This application relates to Internet technology, especially a load balancing method, system, device and storage medium. Background technique [0002] In the Internet field, with the development of product projects, the background system needs to increase the throughput and data processing capacity of the system through horizontal expansion. At this time, it is necessary to load balance the traffic. To put it simply, load balancing means to distribute the traffic to functional units with the same function deployed on different servers. Usually you can use hardware load, this type of load effect is better. In addition, load balancing applications can be introduced, typically nginx, which can forward the traffic accessing the same address to different servers according to a certain load algorithm. [0003] But for the above scheme, the cost is relatively high. Therefore, there are also solutions to search for server nodes through the hash ring to achie...
