Abstract

Cloud computing has important impacts on the environment: data centers – that represent the physical infrastructure where the cloud resources run – are not always designed as green entities, as they consume large amounts of energy (in form of electric power or fuel) often producing significant amounts of CO2 emissions. Such emissions depend on the energy sources used by the data centers and may vary over time with respect to the location in which the data center is operating. To decrease the carbon footprint of cloud computing, the selection of the site where to deploy an application, along with the decision of when to start the execution of the application, should be based not only on the satisfaction of the traditional QoS requirements but also on the energy-related constraints and their dynamics over time.

Goal of this paper is to propose a CO2 emission model able to support emission forecasting, especially for data centers that are based on electricity from the national grid. The proposed emission model can be used to improve the decisions on where and when to deploy applications on data centers in order to minimize CO2 emissions.
