云模式及其在物联网中的应用

针对集群系统中分配节点的单节点失效问题,提出了一种基于云计算系统的集群服务方式,采用全新的自适应云调度策略,完成对最优服务器节点的动态选择。策略以心跳表为基础,通过＂星级服务＂生成不同数目的虚拟服务器组,按照先来先提供服务的竞争机制完成最优节点的选择,保证了当云计算系统的某些部分节点失效时,整个系统仍能继续正常运行,同时也具有自动调整系统负载的作用。最后结合物联网当前面临的难题,探讨了模式在物联网中的应用以及应关注的几个关键问题。

Cloud Mode and its Application in Internet of Things

A method of cluster service is designed on the basis of cloud computing in this paper,which overcomes the single point of failure in the clustered system.The system uses a novel adaptive distributed schedule mechanism to select the best node for the clients.This mode,which is based on the heartbeat table and creates many independent virtual server groups by star service,selects a server among nodes according by the competitive mechanism that first come first to offer a service,and effectively ensures the system failure in some cases,the node can still work,and also dynamically adjusts system loads.Finally,it combines the current probleams of internet of things,and investigates serveral key probleams that internet of things should be pay attention to in using cloud computing technology.
