How Facebook Is Handling All That Really Big Data
Facebook designs its own servers and networking. It designs and builds its own data centers. Its staff writes most of its own applications and creates virtually all of its own middleware. Everything about its operational IT unites it in one extremely large system that is used by internal and external folks alike.MENLO PARK, Calif. -- Facebook is much like the Starship Enterprise in that it likes to go to places no company has gone before. This is probably because not too many IT companies, especially young ones, have had to serve upwards of 950 million registered users -- including a high percentage on a real-time basis -- daily. Not many have to sell advertising to about 1 million customers or have dozens of new products in the works, all at the same exact time.
"So just about everything we do turns out to be a big data problem," said Jay Parikh, vice president of Infrastructure Engineering at Facebook, who spoke recently to a small group of journalists at the company headquarters. "This affects every layer of our stack. We've talked with some of you about the servers, storage, networking and the data center, as well as all the software, the operations, the visibility, the tools -- it all comes together in this one application that we have to provide to all our users." Big data simply is about having insight and using it to make impact on your business, Parikh said. "It's really very simplistic. If you aren't taking advantage of the data you are collecting and being kept in your business, then you just have a pile of a lot of data," Parikh said. "We are getting more and more interested in doing things with the data we are collecting." Facebook doesn't always know what it wants to do with the user lists, Web statistics, geographic information, photos, stories, messages, Web links, videos and everything else that the company collects, Parikh said. "But we want to collect everything, we want to instrument everything: cameras, when that door opens and closes, the temperature in this room, who walks in and out the lobby. "We want to know who visits the site, what activities they do, where they do it on the site. So everything is interesting to us," he said.
