Load Balancing with Nginx: A Complete Guide

Load Balancing with Nginx

Load balancing is a crucial technique for distributing incoming network traffic across multiple servers to enhance performance, reliability, and scalability. Nginx, a powerful web server and reverse proxy, offers robust load-balancing features that make it a popular choice for managing high-traffic websites and applications.

Why Use Load Balancing?

When a website or application experiences high traffic, a single server might struggle to handle all requests efficiently. Load balancing helps in:
