Research On Information Service Based On Cloud Computing

As a new technology, cloud computing has changed IT community profoundly because of more formidable computer power, more storage and lower cost for users. It has reshaped people's life and work style radically which is similar to the internet ten years ago.Due to obvious advantages, cloud computing is developing swiftly. International IT magnates, for example Google, Amazon, IBM, Microsoft, Salesforce, and so on, have rushed to capture computing market. Cloud computing has become a high frequency word in IT community. Cloud computing and its application are infiltrated into various fields widely under the drive of some manufacturers. As far as information service is concerned, Cloud computing is a shared infrastructure. It can coordinate information resources, develop in breadth and depth of information service, reduce service costs and enhance effectiveness. Information service in the big scale becomes more and more precise, professional, self-oriented. The mergence of cloud computing and mobile communication satisfies the power of service'on-demand' whenever and wherever. In this paper, information service system, configuration, main body and service model based on cloud computing are focused on, and some important problems on cloud services are summarized, such as data security, standard and law, and some measures solving these problems are presented.At first, the concepts, principle, advantages and applications of cloud computing are introduced. The academic foundation that cloud computing promotes information service is tracked. The effects that cloud computing has brought to information service are described.Secondly, styles and characteristics of user's information requirements and the superiority on cloud computing meeting user's requirements are discussed.Thirdly, the structure of information service system based on cloud computing is analyzed. Cloud computing has promoted the optimization of information configuration. The dynamic information service configuration based on cloud computing is entirely different from the static one in the internet era. Users in the cloud computing era are not only consumers, but also producer. They are not only experiencers, but also disseminators.Fourthly, in view of four key elements of information service, four information service directions in the cloud computing era are presented.At last, some burning problems such as data security, standard and law are made a summary and some countermeasures for dealing with those problems are discussed.
