The acronym LAMP refers to a solution stack of software programs, commonly free software programs, used together to run dynamic Web sites or servers :
-
Linux , (referring to the operating system );
Apache , the Web server ;
MySQL , the database management system (or database server);PHP (Sometimes Perl or Python ), the programming language .
The combination of these technologies is used primarily to define a web server infrastructure, define a programming paradigm of developing software, and establish a software distribution package.
Though the originators of these open source programs did not design them all to work specifically with each other, the combination has become popular because of its low acquisition cost and because of the ubiquity of its components (which come bundled with most current Linux distributions particularly as deployed by ISPs). When used in combination they represent a solution stack of technologies that support application servers . Other such stacks include unified application development environments such as Apple Computer 's WebObjects , Java / Java EE , Grails , and Microsoft 's .NET architecture.
The scripting component of the LAMP stack has its origins in the CGI web interfaces that became popular in the early 1990s. This technology allows the user of a web browser to execute a program on the web server, and to thereby receive dynamic as well as static content. Programmers used scripting languages with these programs because of their ability to manipulate text streams easily and efficiently, even when they originate from disparate sources. For this reason system designers often referred to such scripting systems as glue languages .
Michael Kunze coined the acronym LAMP in an article for the German computing magazine c't in 1998 (12/98, page 230). The article aimed to show that a bundle of free software could provide a viable alternative to commercial packages. Knowing about the IT-world's love of acronyms, Kunze came up with LAMP as a marketing-like term to increase the popularity of free software. [citation needed] O'Reilly and MySQL AB have made the term popular among English-speakers. Indeed, MySQL AB has since based some of its marketing efforts on the popularity of the LAMP stack.
