What does LAMP stand for?

The acronym LAMP refers to a solution stack of software, usually free and open source software , used to run dynamic Web sites or servers . The original expansion is as follows:

* Linux = operating system
* Apache = the Web server
* MySQL = the database management system (or database server)
* PHP = the programming language. Other than PHP, there are other similar programming languages can also used to enrich some other specific functions. These languages include Perl or Python.

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.

Jonathan Schwartz, CEO of Sun Microsystems, wrote on his blog on Sun on 27 July 2008 shared his latest vision on the impact of open source to the IT industry.

It was an occasion with a customer that triggered his thought. He mentioned the customer who leads technology and operations for one of the world's largest companies. They were talking through his priorities for the upcoming year, and on a page filled with various traditional priorities (consolidation, energy management, disaster recovery, regulatory compliance) were two interesting words.

"Open Source."

The customer told Jonathan that they'd done an audit of the firm's development activities, and found an overwhelming number ("hundreds") of open source projects that had been completed behind the scenes, beyond management's oversight. The projects were designed to solve problems deemed too expensive or difficult to solve with proprietary technologies - from meeting a tough budget, to automating a new process. And rather than fight the trend, they figured it was delivering real benefit, something to explore more fully. And they were asking for Sun's help.

Actually Jonathan is seeing this with nearly every customer he meet, the invisible hand of open source - communities of individuals equally devoted to their employers, and to personal and peer productivity. These communities, within companies as well as across industries, are solving problems without having to involve procurement (while religiously adhering to policies surrounding privacy, intellectual property protection and software licensing). They're delivering unquestionable value.
