Data center and global networks built for AI era
Over the last 25 years of building Google’s global network, we’ve navigated major architectural eras — from the Internet, to streaming, and the cloud. Today, we are squarely in the midst of a fourth: the AI era. The applications in the AI era are fundamentally different from the consumer and enterprise applications of the previous eras and impose a set of novel and demanding requirements — on compute resources, of course, but also on the network.
Consider the fundamental physical challenge, which is that it is far more difficult to move electrons (electrical power) than it is to move photons (data over fiber). Because the demand for AI compute frequently outpaces the space and power capacities of individual facilities, we strategically locate data centers near sustainable energy sources, or in locations with pathways to add clean energy sources to the local grid. Then, by utilizing the network to distribute AI...
