The Evolution of th LAMP Stack

LAMP is an acronym for a solution stack of free, open source software, originally coined from the first letters of Linux (operating system), Apache HTTP Server, MySQL (database software), and PHP, Python or Perl (scripting language), principal components to build a viable general purpose web server.

The exact combination of software included in a LAMP package may vary, especially with respect to the web scripting software, as PHP may be replaced or supplemented by Perl and/or Python.[2] Similar terms exist for essentially the same software suite (AMP) running on other operating systems, such as Microsoft Windows (WAMP), Mac OS (MAMP), Solaris (SAMP), or OpenBSD (OAMP).

Though the original authors of these programs did not design them all to work specifically with each other, the development philosophy and tool sets are shared and were developed in close conjunction. The software combination has become popular because it is free of cost, open-source, and therefore easily adaptable, and because of the ubiquity of its components which are bundled with most current Linux distributions.

When used together, they form a solution stack of technologies that support application servers.

The LAMP stack is widely used because it offers a great number of advantages for developers:

Easy to code: Novices can build something and get it up and running very quickly with PHP and MySQL.
Easy to deploy: Since PHP is a standard Apache module, it is easy to deploy LAMP web applications by uploading .php files to an Apache server and connecting to a MySQL database.
Develop locally: LAMP can be set up so an app can be built locally, then deployed to the Web.
Cheap and ubiquitous hosting: Many inexpensive web hosts provide PHP and MySQL services.
Main article: Linux
Linux is a Unix-like computer operating system kernel. A major emphasis of Linux development is security[citation needed], which makes it an appealing choice for a web-server application. Like the other LAMP components, Linux is free open-source software which means the source code is provided with operating system, which can be edited according to specific needs. Also, because Linux-based operating systems are Unix-like, a Linux server is more natively-compatible with other server-oriented platforms, such as Solaris and BSD, than non-Unix-like systems like Microsoft Windows.

Main article: Apache HTTP Server
Apache is a free software/open source web server, the most popular in use.[7]

Main article: MySQL
MySQL is a multithreaded, multi-user, SQL database management system (DBMS) now owned by Oracle Corporation with more than eleven million installations.[8]

MySQL has been owned by Oracle Corporation since April 20, 2009 through the purchase of Sun Microsystems.[9][10] Sun had acquired MySQL originally on January 16, 2008.

PHP, Perl, or Python
Main articles: PHP, Perl, and Python (programming language)
PHP is a reflective programming language originally designed for producing dynamic web pages. PHP is used mainly in server-side application software. Perl and Python can be used similarly.
