Google's data centers grow too fast for normal networks, so it builds its own

Stephen Lawson | June 19, 2015
Google has been building its own software-defined data-center networks for 10 years because traditional gear can't handle the scale of what are essentially warehouse-sized computers.

The design lets Google upgrade its networks without disrupting a data center's operation, Vahdat said. "I have to be constantly refreshing my infrastructure, upgrading the network, having the old live with the new."

Google is now opening up the network technology it took a decade to develop so other developers can use it.

"What we're really hoping for is that the next great service can leverage this infrastructure and the networking that goes along with it, without having to invent it," Vahdat said.
