Keeping all of Google online is a hard job, but a fascinating one. So we talked to Benjamin Treynor Sloss, the guy who has to do that for a living. We have also interviewed David Gauthier, the person behind Microsoft’s data center strategy, AWS’ Ian Massingham and Facebook’s Delfina Eberly, to learn what makes these companies tick.

This cover feature is a story about giants, and the cost of operating at immense scale. Elsewhere in the magazine, we take a deep dive into the world of cooling, with a special supplement analyzing the hottest markets and the coolest solutions.

Did you know that there’s a great refrigerant shortage? Or that heat can be sent into space? How about using hot water to cool supercomputers?

We also take a look at cloud high availability versus 2N resiliency, discuss how robots and open source technologies are saving retailers, and chart the rise of Funke Opeke, the CEO of MainOne, a company that is intent on bringing West Africa online.
