From New York Times BITS Blog, a post on McKinsey’s recent study on Cloud Computing.

The McKinsey study, “Clearing the Air on Cloud Computing,” concludes that outsourcing a typical corporate data center to a cloud service would more than double the cost. Its study uses Amazon.com’s Web service offering as the price of outsourced cloud computing, since its service is the best-known and it publishes its costs. On that basis, according to McKinsey, the total cost of the data center functions would be $366 a month per unit of computing output, compared with $150 a month for the conventional data center.

“The industry has assumed the financial benefits of cloud computing and, in our view, that’s a faulty assumption,” said Will Forrest, a principal at McKinsey, who led the study.

Owning the hardware, McKinsey states, is actually cost-effective for most corporations when the depreciation write-offs for tax purposes are included. And the labor savings from moving to the cloud model has been greatly exaggerated, Mr. Forrest says. The care and feeding of a company’s software, regardless of where it’s hosted, and providing help to users both remain labor-intensive endeavors.

Clouds, Mr. Forrest notes, can make a lot of sense for small and medium-sized companies, typically with revenue of $500 million or less.
