From "Clouds and Judgement":
"Computing is fast becoming a “cloud”—a collection of disembodied services accessible from anywhere and detached from the underlying hardware. The chances are that much of business and everyday computing will one day be mediated by this ethereal cloud."
I highly recommend the report as it presents an excellent case for disruptive nature of cloud computing.
"In the years to come companies are likely to venture much farther. For one, operators of computing clouds such as Amazon and Google have shown that this is a far more efficient way of running IT systems. Secondly, many firms will find they have no choice. The way in which their IT infrastructure has grown is proving unsustainable. Most corporate data centres today are complex warrens of underused hardware that require more and more people, space and power to keep them going. The current economic malaise will increase the pressure on companies to become more efficient. More has to be done with less, which is cloud computing’s main promise."
