基于云计算平台的学生作业提交系统设计与实现

THE DESIGN AND IMPLEMENTATION OF STUDENTS’ASSIGNMENTS HANDLE SYSTEM BASED ON THE CLOUD COMPUTING PLATFORM

无论C/S结构还是B/S结构,大量客户机同时访问服务器时,会使服务器端负载过大,降低系统性能,严重的会导致服务器宕机。实验课教学中经常会遇到这种情况,即将下课时,学生都要提交上机作业,由于大量数据的上传经常导致服务器瘫痪。针对这种情况,本文搭建了一个实验性云计算平台,并基于该平台使用Hadoop开发了学生作业提交应用系统,让平台中多个节点服务器共同接收数据,以缓解数据对单一服务器的负荷。通过实际应用验证,该系统具有优越的性能,解决了大量数据上传对服务器造成负载过重问题。

For the traditional application based on C/S and B/S architecture, when a lot of clients access server, the server will be downtime. According to teaching practice of us, when the class is over, students should submit their assignments .A large number of assignments data make the server paralyzed. To solve the problem we built up a private Cloud Computing Platform successfully and developed a student’s assignments handle system based on the platform using Hadoop. Experiments show that the platform has a good robustness and could bear large amounts of data upload.
