The real-world architecture of the internet cloud

The internet cloud is actually “giant buildings full of computers and diesel generators”.

Yet as data centers increasingly become the nerve centers of business and society — even the storehouses of our fleeting cultural memory (that dancing cockatoo on YouTube!) — the demand for bigger and better ones increases: there is a growing need to produce the most computing power per square foot at the lowest possible cost in energy and resources. All of which is bringing a new level of attention, and challenges, to a once rather hidden phenomenon. Call it the architecture of search: the tens of thousands of square feet of machinery, humming away 24/7, 365 days a year — often built on, say, a former bean field — that lie behind your Internet queries.
