Simon Wardley, cloud strategist for Canonical, has an interesting take on how green Cloud computing is. It leads to better utilisation of computing resources, and eliminates wastage. But cloud also accelerates building of appliances and triggers an explosion of consumption of energy-intensive computing resources, Sounds simplistic? The piping of electricity to homes, led to a similar explosion of consumption. So, is cloud computing green? Yes in the short run and No in the long run, says Mr Wardley.
