Research On Mobile Information Services Based On Google App Engine

Cloud computing is not only the integration and development of parallel computing, distributed computing and grid computing, but also the commercial implementation of these concepts. Through virtualization technology, cloud computing can improve the resource utilization and management efficiency, and reduce the cost. The resources provided by cloud computing are flexible and scalable, which can be deployed and scheduled dynamicly. With cloud computing. Mobile Internet has a brighter development prospect. In cloud computing, as computing power and storage capacity is provided by cloud, mobile devices can break the bottleneck of hardware restrictions and realize the terminal irrelevance. In addition, as stored in the cloud, the data could be shared among different users, which makes data sharing more convenient.In this thesis, we build the system using the infrastructure provided by Google App Engine. Google App Engine is a Web application hosting platform. It allows users to write their own applications to the Google's storage space. With the help of cloud computing, users can make better use of the broadband network and the server resource. Google App Engine provides distributed data storage service. In this thesis, the column storage mode is studied and implemented with Google App Engine. By introducing two customized fields, data can be non-destructive restored. Some performance tests have proved that the system is suitable for web applications, with frequently read operations. Meanwhile, this thesis designs and implements the mobile terminal applications. Users can enjoy the mobile information services provided by the system. For example, users can search restaurants according to their requirement; users can scan the details of a restaurant; users can locate the restaurant's position. Furthermore, users can post their comments, photos and videos of the restaurant to the cloud.With cloud computing technology and mobile terminal technology, we believe that users can enjoy seamless and wonderful Internet experience in the future.
