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:

- Improving Performance: Ensuring fast response times by routing requests to the least busy server.
- Enhancing Reliability: If one server fails, traffic can be rerouted to healthy servers.
- Scalability: Making it easier to add more servers as traffic increases.
