Calculating the carbon footprint of virtual desktop infrastructure
The Green Cloud Computing research project (in German) analysed the carbon footprint of a computer workspace equipped with virtual desktop infrastructure (VDI) as compared to the classical solution. VDI means that the entire computer desktop in the data centre has been virtualised. All the specific settings, software products and data are no longer installed on the local computer but on a server in the data centre. This no longer requires the standard PC and energy-saving thin clients can be used instead, which serves as the interface to the server. Our calculations conclude that a workstation equipped with a VDI (thin client computer) generates 33 kilograms fewer emissions than a workstation using a notebook or a desktop PC. The calculations include the manufacturing costs for the hardware in the data centre and for the local thin client computers as well as the power consumption in the data centre and at the workstation. However, the sensitivity analysis shows that it is not always more favourable to the climate to move IT services to the cloud. What is important is the equipment of the local workstation, how IT is utilised and whether the infrastructure of the data centre is geared to requirements.
