Dynamic VM placement method for minimizing energy and carbon cost in geographically distributed cloud data centers

Abstract

Cloud data centers consume a large amount of energy that leads to a high carbon footprint. Taking into account a carbon tax imposed on the emitted carbon makes energy and carbon cost play a major role in data centers' operational costs. To address this challenge, we investigate parameters that have the biggest effect on energy and carbon footprint cost to propose more efficient VM placement approaches. We formulate the total energy cost as a function of the energy consumed by servers plus overhead energy, which is computed through power usage effectiveness (PUE) metric as a function of IT load and outside temperature. Furthermore, we consider that data center sites have access to renewable e..
