Drupal & Nginx
Drupal and Nginx work great together. I have been using Nginx with PHP-FPM and previously PHP-CGI instead of Apache since 2011. I have grown to love the little engine that could. It has a much lower memory usage footprint, and responds much faster than Apache in my experience.
Here are some cool and useful settings for Nginx and Drupal that will help you on your way to running your Drupal website on an Nginx web server.
