What does it take to power the Cloud?

Depends on the Cloud data centers (Data Centers) energy guzzlers. Their modernization is now essential to reduce the energy bill. A graphic summarizes the current situation and future prospects ... AAB, an American company that develops automation technologies to improve energy efficiency while reducing environmental impact, has just completed a very educational graphic that puts into perspective the consumption Current Cloud and its cumbersome infrastructure.

It gathers and puts into perspective the latest statistics on emissions of CO2, cooling needs and power needed to operate large data centers that power the Web services and information. As she explains, "Every time you download a video, photo sharing, send an email, tweet or a position control the balance of a bank account, used the device queries a data center.

The latter is composed of rows of servers that store petabytes of information in complex energy guzzlers. " It finds that these data centers are responsible for 2% of global CO2 emissions annually and employ 80 million megawatt hours. This represents 1.5 times the amount of electricity used to power New York for a year.

We also learn that 10% of installed servers are unused because of planning policy needs overly optimistic. But the energy used to power these servers is a CO2 emission equivalent to 6.5 million vehicles! Cooling of Data Centers account for nearly 30% of the total energy consumed by them.

A bill which amounts to 281 million. If all the international data centers adopting the latest technologies of power (which show a success rate above 97%), savings would fuel a iPad for 70 million years! You can compare this to another computer graphics produced by Wikibon which graphically summarizes the extent of cloud.
