It’s like the last revolution where the shift was from everyone generating their own power, to centralized power generation facilities. Tremendous economies of scale in cloud computing.
A Microsoft study bears out what environmentally-conscious companies have hoped for all along: cloud computing has the potential to reduce energy consumption and carbon emissions by 30 percent or more.
Large data centers, like those run by tech giants Microsoft and Google, benefit from economies of scale and operational efficiencies, according to the study. Small businesses, of about 100 users, moving business applications away from on-site servers into the cloud can see net energy and carbon savings of more than 90 percent, the researchers wrote. For mid-sized organizations, of about 1,000 users, the savings were between 60 to 90 percent, according to the Microsoft-commissioned study.
