Three ways to load balancing nginx

nginx load balancing provides the following three ways: 1. Polling: forward the requests one by one to the backend server; 2. Weighted polling: allocate requests based on weights; 3. Minimum connection: forward the requests to the server with the least active connections.

Three ways to load balancing nginx

nginx is a popular and powerful web server that provides multiple load balancing mechanisms that can improve application availability and performance. The following are three main ways to load balancing nginx:

1. Poll

Polling is the easiest load balancing algorithm that forwards requests one by one to the backend server. This approach is easy to implement and has low overhead, but it does not take into account the load of the server or the performance of the application.

2. Weighted polling

Weighted polling is an extension of the polling algorithm that allows administrators to assign weights to the backend server. Servers with higher weights will handle more requests, and servers with lower weights will handle fewer requests. This method can load balancing according to the server's processing power.

3. Minimum connection

The minimum connection algorithm forwards the request to a backend server with minimal active connections. This approach aims to reduce the load on each server, thereby improving overall performance. However, it can cause requests to be distributed unevenly between servers, especially when the server's load changes rapidly.
