Facebook frequently appraisals whether to carry on utilizing its own data centers or take off its dispensation to a cloud service supplier, and its operations stay on home-based infrastructure.

"We look at, most likely one time or twice a year, does it create sense for us to build more infrastructure in the cloud, plus on someone also backbone, and fewer for ourselves?" said Jonathan Heiliger, vice president of technical operations at Facebook, in an live talk at the Structure 2010 conference in San Francisco. "We've resolute, for two causes, that it doesn't, every time we've done this analysis," Heiliger said.

"It provides us a quality of elasticity. We don't have to stay for someone to go expand a characteristic. We now revolve it out ourselves," Heiliger said.

By utilizing its own infrastructure, Facebook can put in a dissimilar CPU architecture, add a novel networking device, or bring in traffic speeding up when and where it likes.

The company is also free to shift traffic about and put caches where it creates the majority sense, he added.
