How does Facebook store tons of user profile data?

Facebook is the fastest growing social networking site in the world today with up to 250,000 new users being added every day.

But ever thought How does Facebook store and retrive this massive amount of data? Well, heres the answer..
  Facebook wants new designs for storage and other equipment that are more energy efficient. Its year-old project to create open source hardware for data centers got a major boost when a whole bunch of big players joined including HP, AMD, Fidelity, Quanta, Salesforce.com, VMware and Canonical.


But there's a catch. Companies that participate have to agree to "open source" their designs and make them available for free to anyone that wants them.

Well we get a feeling that Facebook's goal here is to do for hardware what Linux did for software. That means create open source hardware where users are calling the shots, not just hardware vendors.

Project Loon - Google's Wi-Fi balloon experiment

Google Lab, which came up with a driverless car and web-surfing eyeglasses was working from the past 18 months on what Google calls 'Project Loon'. Google launches giant balloons over New Zealand's south Island, carrying computer equipment that can create a high-speed internet infrastructure

If successful, the technology might allow countries to leapfrog the expense of laying fiber cable, dramatically increasing Internet usage in places such as Africa and Southeast Asia.

The fully solar powred balloon fly free and out of eyesight. Each balloon would provide Internet service for an area twice the size of New York City, about 1,250 square kilometers (780 square miles).



The signals travel in the unlicensed spectrum, which means Google doesn’t have to go through the onerous regulatory processes required for Internet providers using wireless communications networks or satellites.

Google in the next phase of the trial they hope to get up to 300 balloons forming a ring on the 40th parallel south from New Zealand through Australia, Chile, Uruguay, Paraguay and Argentina.

 Google itself also stands to benifit as it expand its own empire by bringing Internet to the masses: More users means more potential Google searchers, which in turn give the company more chances to display their lucrative ads..
