云计算在硅谷不像是一场革命，而只是一种选择，在很多时候，这也是不得不做的选择：没那么轰轰烈烈，而是静悄悄地日新月异。
Silicon Valley,home to many of the most famous universities,the world's largest technology corporations,and most celebrated investment organizations,never lack of talents,capital,innovation or opening up in the last more than 50 years.Of cause, in the wider range,it is also supported by the better trust mechanism and spirit of the credit contract in the whole US society. All of these make a virtuous cycle among cloud computing,developers and corporate customers. Additionally,sluggish economic environment enables cloud computing to be popular.In 2008 when the US was haunted by the serious subprime mortgage,the whole high-tech industry was badly hit,and it became common of reducing budget,layoffs, and shrinking business.But during that period,a large number of 'cloud companies' won their first bucket of gold in the area of cloud computing. All of these brought an interesting phenomenon that cloud applications were not like a revolution,but only a choice in Silicon Valley.In many cases,this was a choice we had to do.
