Apache and Nginx are free, open-source and the most widely used web servers in the world. Apache is the number one server, while Nginx comes in the second place. Apache is known for its power and the backend compatibility while Nginx is known for its speed. Nginx provides a rich set of features including load balancing, security, and acceleration. Using Nginx as a reverse proxy allows you to use these features for any web application.

Configuring a reverse proxy helps you to hide the identity of your backend servers and protect your servers from attacks.
