most all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking, Programming tools, even communication services and collaboration（72）．

Cloud computing began as large-scale Internet service providers such as Google, Amazon, and others built out their infrastructure. An architecture emerged: massively scaled, （73）distributed system resources, abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on（74）"somewhere on the Internet" and the application runs on both the "cloud servers" and the user's browser.

Both clouds and grids are built to scale horizontally very efficiently. Both are built to withstand failures of （75） elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. What's more, clouds expand the types of resources available - file storage, databases, and Web services - and extend the applicability to Web and enterprise applications.

ilities of what can be achieved. A decade ago, the cellphone was a bulky item of limited range, high cost and minority interest. Now it is everywhere.

The personal computer (PC) has been around for decades. But it was only in the mid-1990s, with the explosive growth of the Internet and the World Wide Web, that it was first recognized that the technology can be used to do business. It is now fully recognized that shopping in cyberspace, the name given to this world wide electronic network, is the way of the future.

A recent study by the Department of Trade and Industry (the DTI) provides some impressive data. In the United States, the world' s largest consumer of goods， about 21% of the population is now online. Europe is still behind, with only 10% in Britain,for example. But, as we've seen before, when it comes to technology, nothing stays the same for long. The number of people online is rising dramatically throughout the world.
