Will 2012 Be the Year of the Private Cloud?
As business adoption of cloud computing and cloud storage takes hold, new benefits of cloud IT versus traditional IT continue to emerge on a regular basis. One recent example is the Carbon Disclosure Project Study 2011: Cloud Computing – The IT Solution for the 21st Century produced by analyst firm Verdantix. In the report, not only are the cost advantages of cloud computing discussed but also the resulting reduction in greenhouse gas emissions. Specifically, the study looks at a food and beverage company that is moving an HR application from local IT to the cloud. The model predicts a savings of $12 million over a 5 year period and a reduction of 30,000 tons in CO2 emissions, simply by moving to the public cloud.
So what does all this have to do with 2012 being the year of the private cloud? Let me explain. Interestingly enough, the study also concluded that this same company could save $5M and cut CO2 emissions by 25,000 tons over the same time period but this time by moving to a private cloud. While most of us already assume that public clouds are housed in highly efficient “green” data centers with tremendous economies of scale, the private cloud scenario modeled in this report makes a strong statement that improved resource utilization can drive huge benefits even when all infrastructure stays local. The study goes on to cite other efficiencies of cloud architectures including improved time-to-market which also apply to both public and private clouds…
