LEMP is an excellent alternative to traditional LAMP servers. Nginx is lighter weight and faster than Apache in some situations. It can also be configured to do other useful things, like serve as a reverse proxy. Just like with LAMP, Debian is an excellent platform for LEMP servers. Everything you need is available in the Debian repositories, so it's simple to get started.
