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 these challenges, we required the parameters that have the biggest effect on energy and carbon footprint cost to propose more ef?cient VM placement approaches. In this work, we calculate the total energy cost consumed by servers plus overhead energy, which is computed through power usage effectiveness (PUE) metric as a function of IT load and outside temperature. The main contribution of this work lies in comparing the different VM placement approaches by calculating the cost of energy consumed and the carbon tax and we also consider total available renewable resources in the datacentre site and carbon footprint cost. This study shall help the cloud providers to select the best VM placement approach to minimize their maintenance cost of a datacentre.
