Design And Optimization Of Cloud Platform Of Instructional Resouces Based On Hadoop

With the informationization in colleges and universities,the teaching resources have been changed correspondently.First of all,the number of instructional resources sharply exploded.Secondly,data structure presents diversity,including both structured and unstructured data.So the traditional instructional resources platform which is based on centralized server management already cannot meet this demand.For us,it is a new chanllenge to build and develop instructional resources platform.And the development of cloud computing technology is of great help to solve the problem of big data.In order to meet both colleges’ and universities’ demand,this paper,based on the Hadoop cloud platform,builds,tests and optimizes cloud platform of instructional resources.Finally,analysis and evaluation was discussed.At first,this paper illustrates the theoretical and practical significance of instructional resources platform based on cloud computing technology,the background and purpose of the study.At the same time,the combination of cloud computing technology and instructional studies both at home and abroad are analyzed.Then,the related technology and theory on cloud computing and the instructional resources platform is presented.And the framework of cloud computing technology,as well as virtualization technology is introduced.The relationship between cloud computing and big data,along with the Hadoop ecosystem is analyzed.Secondly,this paper expounds the usage of VMware software,and the process of building Hadoop open source software on the virtual computer cluste.And the brief analysis of the performance has carried on.This paper analyzes the present demand for the platform of instructional resources.Accordingly the platform of instructional resources based on Hadoop framework is built.Firstly,the function module of instructional resource platform is designed,the overall structure is put forward;Secondly,according to the analysis of the data characteristics and structure of current instructional resources,it is put forward to using a different database management systems to deal with the structured and unstructured data respectively.And the process of how to use MySQL to build structured database and how to use HBase to build unstructured databases is expounded.The process of designing web pages for platform of instructional resources is introduced.This paper analyzes the characteristics of instructional resource data,including size,format,types,ect..According to these characteristics,the combination of the Hadoop cloud platform of HDFS storage and the running of MapReduce is designed,tested and analyzes comparatively.Hence,the related conclusion is made that is instructional resource data storage can be optimized in the cloud platforms.Finally,in this paper,the whole process of building platform is summarized and evaluated,so as to provide theoretical reference and practical experience on the application of cloud computing technology on the instructional resources...
