A software stack is a set of software tools bundled together. LEMP stands for Linux, Nginx (Engine-X), MariaDB/MySQL and PHP, all of which are open source and free to use.

It is the most common software stack that powers dynamic websites and web applications. Linux is the operating system; Nginx is the web server; MariaDB/MySQL is the database server and PHP is the server-side scripting language responsible for generating dynamic web pages.
