What is Nginx?

A high-performance web server and reverse proxy known for its stability, low resource usage, and ability to handle many concurrent connections.

Nginx (pronounced "engine-x") serves as a web server, reverse proxy, load balancer, and HTTP cache. Its event-driven, non-blocking architecture handles thousands of concurrent connections efficiently.

Common uses include serving static files, proxying to application servers (PHP-FPM, Node.js, Python), SSL termination, and load balancing. Configuration uses a declarative block-based syntax.
