云计算环境下的流量控制和负载均衡策略

传统的web应用使用专用的硬件资源,这些硬件资源仅为某种特定的应用提供服务。而在云计算环境下,许多不同的web应用需要共享云平台资源。因此,当将传统的web应用迁移到云平台下时,将会出现一系列的挑战,主要的问题是面对大量不同应用请求时的流量控制和负载均衡控制。基于此,提出了云计算环境下的分布式路由系统Distributed Routing System(DRS),DRS主要用于解决当许多web应用在云环境下同时运行时面临的流量控制和负载均衡问题。实验表明DRS能够有效地转发应用请求到后台轻负载服务器,并且有着较低的时延。

Flow control and load balance policy in cloud environment

Traditional web applications used dedicated hardware resources which provide services to a particular application.In the cloud computing environment,a number of different cloud platforms for web applications needing to share resources.Therefore,when traditional web applications migrated to the cloud platform,there will be a series of challenges for web applications.The main problem is facing a large number of requests for different applications and load balancing control and flow control.This paper presents a routing system in cloud environment,Dristributed Routing System(DRS).DRS is mainly used to solve flow control and load balancing problems in cloud environment facing many web applications.Experiments show that the DRS can be effectively applied to forward requests to back-end servers,and it has lower time delay.
