摘要：The Web, which began as a global hypertext system, has evolved into a distributed application platform, in which the application logic and user interface are two separate entities. As we move toward the next generation Web platform, Web 2.0, from Web content to Web of applications, the bulk of user data and applications will reside in the network cloud. Web applications are a critical part of Internet infrastructure and are used for banking, email, financial management, online shopping, auctions, social networking, and the like. Corporations such as Amazon, Google, Microsoft, and Yahoo expend considerable effort to keep up with the growing demand for communication-heavy Internet services which require image and video sharing, social networking, and searching. There is a shift from displaying information using locally installed programs towards displaying information on a browser. For example, the Google Docs word processor and spreadsheet is already visible when using simple e-mail services such as Google Gmail. In this paper, we emphasize the connection between cloud computing and what is now called Web 2.0; we list the advantages of cloud computing, and survey challenges and issues related to cloud computing.
