The informationization is an important support to promote the balanced development Chinese compulsory education, however, it was restricted seriously by existing problem of lacking infrastructure, teachers deficiency, lacking information technology personnel and so on. Therefore, through analyzing the informationization of Chinese rural education, this article proposed that the development and application...
Currently, the e-government tends to take service as its core, while cloud computing has the characteristics of providing information technology in the way of service. This paper presents that e-government system can take advantages of cloud computing to change its function towards service, promote the industrial upgrading and push forward the green technology. We provide detailed analysis of the...
Cloud computing aims at sharing all resource completely, which include CPU's computing ability, store capacity, network bandwidth and etc. Most cloud computing users task requisitions are among multiple target requisition which are hard to be met by these requisition conditions simultaneously. So it is the key to find out the most approximate node machine among large number of node machines in cloud...
Cloud computing is a hot spot of current research, involving distributed storage and distributed computing and other aspects. In view of the requirements for massive data processing and analysis, this paper analyzed the distributed computing platform based on Hadoop, and designed a Hadoop-based distributed database system model. It provides a feasible approach for the development of cloud computing...
The service and cloud computing oriented architecture is a very promising architecture for practical implementation of the next generation geographical information systems. This paper investigated the service and cloud computing oriented architecture for constructing a distributed and web service enabled geographical information platform for labor and social security applications. The spatial cloud...
This paper introduces the concept, development, key features, applications of cloud computing. The difference to grid computing is discussed. Eight kinds of typical open source cloud computing projects are described, the security reference models of cloud services are given. Cloud computing security challenges and countermeasures are discussed in this paper.
The emergence of cloud computing was the result of the development of parallel technology, software technology, network technology. Cloud computing ultimate goal was to service users. Cloud computing could provide users with on-demand computing power, storage capacity and application service capability. As a new model of Internet applications, cloud computing could be the dominant mode to get services...
Currently, there are many algorithms used to balance the task of Cluser-servers, but not sufficiently take into account common method of heterogeneous servers and real-time load condition in each servers; In cloud computing environment, these algorithms don't adequately consider the loade-balacing in the environment of heterogeneous cloud. The paper proposed a Cloud Loading Balance algorithm, adding...
