Microsoft's plans to expand its server footprint and build more data centers will be based on the principal of focusing on power management.
Reports that said the company has already planned for 15 times more power use were dismissed by John Dwyer, Microsoft's international area data center manager.

The company will continue to build data centers and deploy more servers but said that even as the business scales it will work to use less power through better heat management in high density computing environments and management at an application architecture level.
Dwyer told ZDTWEB.com: "We're scaling to meet the demands of our online business strategy. We'll continue to scale the capacity but we don't want to see power use growing in line with compute capacity. We'll have significantly higher capacity with significantly lower PUE. (Power Usage Effectiveness)
The use of container based data centers is a differentiator with Microsoft working to exploit the heat management advantages delivered through a modular design.
Another example Dwyer gave was the use of the management of resilience and redundancy at an application architecture level.
"I can spend $40 million on power redundancy at a facility and that is a spend I have to make every time I build. Or I can spend $40 million once on an applications architecture as a one time investment and use it as IT grows.
"Some of the things we are designing into the Dublin facility (Dwyer is currently overseeing the construction of Microsoft's giant $500 million data center in Ireland's capital) in terms of looking at more efficient cooling and more efficient power density are built on the principals that we learned at our Quincy, Columbia, Chicago and San Antonio data centers.
