2 . Cloud computing will be in use by about 80 percent of about 600 companies. The trend suggests that data management and storage are moving to cloud computing sellers on a large scale.

Touting(兜售)cloud computing as a way to get rid of the costs of buying and maintain in on-site information-technology equipment, sellers offer it in the form of Software AsA. Service(SAAS), a delivery model in which software applications are delivered to customers over a web-based network. SAAS can serve the needs of entire companies through huge, web-based platforms. As cloud computing rapidly bccomes the delivery channel for software developers of all shapes and sizes to get their products to market, offering applications in a cloud is now the rule not the exception. A. relatively small number of sellers are able to offer SAAS to big companies that want company-wide cloud computing, and only the sellers need apply. Although market-share data are hard to come by, the list of company’s large enough to offer cloud-computing on this scale is short: Microsoft, Amazon, Google, Salesforce, Rackspace and not many others.

The concentration of data and virtual (虚拟)computing in the hands of relatively few sellers raises an important risk for their customers if the Internet-based systems of any one seller are hacked, the result could be security problems across entire industries in which their customers do

Can this small group of cloud-computing sellers effectively respond to the needs of their customers to quickly fix such a problem and, most importantly, cut off the damage to these companies' own customers? Don't think such things can't happen. If hackers can penetrate the Department of Defense, the risk that they will penetrate Microsoft or google cannot be ruled out Compromise of just one of these sellers---even one with a modest market share---possibly could shut down, at least temporarily, a sizable part of the U. S. economy.

A．To warn people of the hackers' power.

B．To show relationship between it and microsoft.

D．To present the real picture of the U.S.economy.

4. What might be the best title for the text？

A．The Unthinkable risks of the cloud.
