The PUE (Power Usage Effectiveness), a valid indicator of "Green IT" measurement for the Cloud?
Image : Pixabay Qu’est-ce que le PUE ? What is PUE? The acronym is not well known in the world of IT. It must begin to be understood by data center experts. But in these times, it risks being put on the front of the stage. IT weighs more and more heavily on the front of greenhouse gas (GHG) emissions, and the storage of information has a significant part of it. The European Commission has estimated data center consumption in Europe at 76.8 TW/H, i.e. 2.7% of EU electricity demand, with a projection of 100 MW/H in 2030, i.e. an increase of 28% . In this time of massive switch from infras to the cloud, it was important to define the possible benefits of this storage mode also according to a “Green IT” approach. PUE is defined by dividing the amount of energy needed to run a data center, and the energy needed to run the “equipment” it contains: Since the energy required to operate servers is relatively intangible when the equipment is recent, data center managers will have an inter
