The LAMP stack is easily one of the most popular web server stacks in the world, and that's nothing new. LAMP has been powering a huge portion of the Internet for quite some time. If you're an open source purist or you just don't care for Oracle as a company(a lot of Linux users don't), you can choose to set up a LAMP server on Ubuntu using MariaDB instead of the traditional MySQL. MariaDB is an open source drop-in replacement that was forked from MySQL several years back. It's an excellent solution for LAMP setups where you want to avoid Oracle's open source database.
