Cloud computing is parallel computing, distributed computing and grid integration and development, but also the commercial implementation of computer science concepts. Cloud computing through virtualization technology to increase the efficiency of resource use and management, reducing costs. Cloud computing resources are resilient scalable, dynamic deployment and scheduling can be an efficient way to meet business development needs. With cloud computing, mobile Internet has better prospects for development. In cloud computing, because computing power and storage capacity are all from the \Further, since the data stored in the cloud, the data can be shared between different users, and enhance the convenience of data sharing. The system uses Google's App Engine provides infrastructure to build and deploy applications. Google App Engine is a cloud computing service platform as a service in a typical representative, it is a Web application hosting platform that allows users to write their own applications published to Google's storage space, with the aid of cloud computing technology, play network bandwidth and server resources, a huge advantage. Google App Engine provides the use of a distributed data storage services, this paper studied the column-store this memory mode, and achieve a data type column in the clouds opened stores. By introducing two custom domain R and D, the column can be lossless data storage reduction, and can not involve other conditions unrelated domain analysis part of the data, to improve query efficiency. In addition, this test the efficiency of the system handle concurrent requests and queries, modify, delete data, time-consuming, experiment proves the system is suitable for read operations more frequently, modify, delete less web applications. Meanwhile, this paper designs and implements the system's mobile terminal application, through the cloud server-side and mobile terminal combination, users can enjoy the system provides mobile information services. The restaurant information, for example, the user can retrieve the restaurant according to their needs, you can view the details of a restaurant, you can locate restaurant locations, use the navigation feature to view driving directions. Also, users express their comments in a restaurant, upload photos and video files restaurants. As cloud computing technology and the development of terminal technology, with the power of the Internet, I believe that the future of cloud computing can provide users with a high experience level to build a seamless Internet experience.
