If anyone tells you open source can’t run a large business or scale, remind them that Facebook is serving a half billion people with a network built on open source code. Quite a bit of it, as Developer.com notes, much of what runs Facebook is open source languages and software. At an open source conference, the company discussed how it all works.
Facebook connects its 500 million users using an array of open source software to enable social networking as well as data intelligence. Facebook’s open source Web serving infrastructure has a lot more than just the traditional LAMP (Linux/Apache/MySQL/PHP) stack behind it.
During a keynote session at the OSCON open source conference, David Recordon, the senior open programs manager at Facebook, detailed the infrastructure in use today at Facebook.
