Cloud Computing has the potential to have a massive impact, positive or negative on the future carbon footprint of the sector. It may lead to an increasing demand for energy to power large datacentres or those very datacentres may shift the location of traditional computer resources from relatively inefficient local machine rooms to the extremely efficient plants of computation that are now being developed.
We have undertaken a systematic literature review of recent work in the areas of Cloud Computing and Energy Aware Computing in an effort to understand how Large Scale Complex IT systems consume electricity and what steps may be taken to improve their efficiency.
Investigations are underway at the Cloud Computing Co-Laboratory in St Andrews (StACC) to investigation the connection between workload and power consumed by computing devices. We approach this challenge by offering a Eucalyptus Private Cloud service to users and monitor the subsequent power and resource usage of the provisioned virtual machines.
