NGINX (pronounced "engine x") is a free and open-source web server that is widely used to host websites and other web applications. It is known for its high performance, stability, and low resource utilization, which make it a popular choice for hosting high-traffic websites and applications.
NGINX is a lightweight web server that is designed to handle a high volume of requests efficiently. It is often used as a reverse proxy server, which means that it sits in front of one or more web servers and forwards requests to them. It can also be used as a load balancer, which distributes incoming requests across multiple servers to improve performance and reliability.
