基于云计算的网络教育培训系统研究与实现

Research and Implementation of Network Education and Training System Based on Cloud Computing

针对电网企业网络教育培训系统集中部署产生的访问峰值问题,提出基于云计算建设动态可扩展应用系统的设计方案,并给出系统架构,包括动态集群扩展、基于订阅-发布模式的共享消息总线的系统集成、系统数据解耦等关键技术。通过搭建实验环境,模拟大并发压力下动态调配资源支撑业务需求的场景,结果证明,基于云计算的网络教育培训系统能够满足大并发访问压力下的动态资源需求,保证用户的访问体验。

With the power grid enterprises network education training system concentrated deployment,the system faces a business peak traffic.To solve this problem,this paper presents a design idea of construction of dynamically extensible application system based on cloud computing,puts forward the system architecture.It includes dynamic cluster extension,system integration based on sharing message bus of publish/subscribe model and data decoupling.Through constructing experimental environment,it simulates the scene that through dynamic allocate resources to support the big concurrent access pressure.The simulation results show that the network education training system based on cloud computing can meet the demand of resource for big concurrent pressure,and ensure the user experience.
