The Linux version is called LEMP

The LEMP stack configured in these documents is established in contrast to the popular LAMP Stack used to power many popular web applications. "LAMP" refers to a Linux-based operating system, the Apache web server, the MySQL database server, and the PHP programming language. It is common to substitute other programming languages like Python, Perl, and even Ruby for PHP. The "LEMP" configuration replaces the Apache web server component with nginx (pronounced "engine x," providing the "E" in LEMP) to increase the ability of the server to scale in response to demand. Furthermore, these guides provide instructions for deploying applications written in Python and Perl in addition to PHP, and for configuring the PostgreSQL database as an alternative to MySQL if your applications support this database server.
