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:

• Distributing Traffic: Preventing any single server from being overwhelmed.
• 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.

How Nginx Handles Load Balancing

Nginx can act as a reverse proxy and distribute requests to multiple backend servers using different load-balancing algorithms. The most …
