LAMP is an acronym for Linux / Apache / MySQL / Perl or PHP, a common and popular application stack which web-based applications are built on. In particular many open source projects take advantage of this stack.

• Linux is an open source operating system
• Apache HTTP Server is a popular open source web server
• mySQL is an open source RDBMS (Relational Database Management System)
• PHP or Perl are server-side programming languages which are well interfaced with Apache

Many Linux distributions implements natively a LAMP solution, including all the needed packages.

Variations

Other languages can fit with the "P" letter and are used interchangeably in place of PHP or Perl. Python is a popular example.

There exist also variations of this stack at the operating system layer as well.

• A WAMP stack is one where the operating system is Microsoft Windows.
• The MAMP acronym is also used for Macintosh computers (UNIX-based Mac OS X replaces the operating system layer).
• A SAMP stack is where Sun Microsystems enters the web development arena replacing the operating system by Solaris.
