Research And Application Of Digital City Based On Cloud Computing Data Center

With the acceleration of the urbanization process in our country, city scale isexpanding unceasingly and urban management issues have become more and more serious.Digital city which has been proven to be an effective solution has got lots of attentionsfrom many experts and scholars and city managers. The continuous improvement of newtechnology has laid the solid hard foundation for the development of digital city. Theconstruction of digital city in western countries has already started and in domestic, thegovernment-led pilot projects are in full swing as well. The research work done in thisarticle is just against this background. The thesis carries on in-depth analysis anddiscussion on the system architecture of digital city which has a positive significance tothe construction work in our country.Firstly, this thesis makes an overview on the related concepts, including the basicconcepts, current construction situation and theoretical foundation. And then introducesthe system architecture technology of digital city system and the related techniques of dataflow. Subsequently, based on the integrated public platform and cloud computing datacenter, the framework of digital city and analyze its structure and data flow are proposed.Secondly, in order to meet the requirements of magnanimous data management, thethesis designs the cloud computing data center and the corresponding management systemwhich can realize data exchange and sharing, dynamic disposition of system resources andautomatic data management including disaster recovery and backup. Considering that thesystem should response to service request fast and flexibly, the integrated public platformwhich mainly involves information service and data management subsidiary by the waysof Web Service is proposed.Thirdly, the thesis designs the integrated application system of digital citymanagement under the main framework above. The thesis provides an overview on digital city management concepts, and then designs the digital city management process andanalyze the data-functional flowchart of the management subsystem in detail.There is a full-text summary in the end. Some pending questions that needed to bestudied further is proposed.
