Research On Information System Architecture Based On The Cloud Computing Environment

With the development of virtual technology, distributed technology, data processing technology and other key cloud computing technology as well as the traditional system structure of information system of high cost, poor allocation of resources and other so many problems appear, more and more attention paid to the fusion of cloud computing technology with the traditional information system architecture.Cloud computing from the "resource sharing, distribution according to needs" concept, using virtualization technology, the enterprise IT restructure integration for the unification of the virtual resource management, according to the different needs of each department information system to each according to his need, at the same time, according to the information system for dynamic load allocation, so as to achieve the increasing the service efficiency of the hardware, reduce the cost.The main research content of this paper is divided into several parts as follows:Firstly, Based on the study of the Hadoop framework, this paper puts forward a kind of methods to improve the efficiency of Map Reduc model, and verifys the feasibility and superiority of this method with experiments. The method based on Hadoop FIFO(First Input First Output) strategy, adds a job queue to store the jobs which locality need to be optimized, so as to optimize local job tasks, reduces the network resource consumption of the Hadoop framework, also be to reduce the total execution time of operation.Secondly, Based on the research of the traditional information system architecture, puts forward a cloud environment information system architectur with sensing layer,transport layer, application layer.Finally, studies the characteristics of the information system architecture of the cloud environment, analyzes the information system of the cloud environment advantage, realize transportation information system in a cloud environment, and compares the system test. Information system architecture is proposed in this paper has certain superiority in the cloud environment.
