About Facebook

Founded in February 2004, Facebook is a social utility that helps people communicate more efficiently with their friends, family and coworkers. The company develops technologies that facilitate the sharing of information through the social graph, the digital mapping of people's real-world social connections. Anyone can sign up for Facebook and interact with the people they know in a trusted environment.

Product

Facebook, the product, is made up of core site functions and applications. Fundamental features to the experience on Facebook are a person’s Home page and Profile. The Home page includes News Feed, a personalized feed of his or her friends updates. The Profile displays information about the individual he or she has chosen to share, including interests, education and work background and contact information. Facebook also includes core applications – Photos, Events, Videos, Groups, and Pages – that let people connect and share in rich and engaging ways. Additionally, people can communicate with one another through Chat, personal messages, Wall posts, Pokes, or Status Updates.

Technology

Facebook is one of the most-trafficked sites in the world and has had to build infrastructure to support this rapid growth. The company is the largest user in the world of memcached, an open source caching system, and has one of the largest MySQL database clusters anywhere. The site is largely written in PHP though the engineering team developed a way to programmatically transform PHP source code into C++ to gain performance benefits. Facebook has built a lightweight but powerful multi-language RPC framework that seamlessly and easily ties together infrastructure services written in any language, running on any platform. The company has created a custom-built search engine serving millions of queries a day, completely distributed and entirely in-memory, with real-time updates. Facebook relies heavily on open source software and releases large pieces of its own software infrastructure as open source. See http://facebook.com/engineering and http://facebook.com/opensource.

Platform

Facebook Platform is a development platform that enables companies and engineers to deeply integrate with the Facebook website and gain access to millions of users through the social graph. Facebook is a part of millions of people’s lives all around the world providing unparalleled distribution potential for applications and the opportunity to build a business that is highly relevant to people’s lives.

Privacy, Safety and Security

Facebook has always focused on giving people control over their experience so they can express themselves freely while knowing that their information is being shared in the way they intend. Facebook's privacy policy is TRUSTe certified, and Facebook provides simple and powerful tools that allow people to control what information they share and with whom they share it. More information can be found at http://www.facebook.com/privacy/explanation.php. From its beginning, Facebook has worked to provide a safe and trusted environment by, for example, requiring that people use their real names. Facebook also works with online safety experts around the world and has established a global Safety Advisory Board that it consults with on safety issues.
