A.k.a. Swamp cooling, is a strategy for cooling air that takes advantage of the drop in temperature that occurs when water that's exposed to moving air begins to vaporize and change to gas.   

A.k.a. Containerized or Modular data center,  is a self-contained computing facility that is manufactured in a factory and shipped to a location. 

A metric used to determine the energy efficiency of a data center. The metric, which is expressed as a percentage, is calculated by dividing IT equipment power by total facility power.

The convergence of IT and data center facilities functions to improve the efficiency of energy use, optimize equipment layouts, support virtualization and consolidation, develop strategic planning and enhance data center availability.
