为了提高云服务系统的安全可靠性,提出了一种云计算环境下中间件的负载均衡机制。确定负载粒度,考虑影响中间件负载的各种参数,设计参数的加权因素和负载算法,建立监控模型,及时反应负载变化;建立中间件负载均衡结构模型,设计均衡算法,实现各个中间件的均衡,保障云服务安全可靠。仿真结果表明,该负载平衡机制能有效地实现云计算环境下服务中间件的负载均衡。

To improve security and reliability of cloud services system, a load balancing mechanism of middleware is presented. First, the load granularity is determined, considering various parameters which will impact the load of middleware, the weighting factors of parameters and the load algorithm are designed, a monitoring model is built which will reply the change of load imme- diately. Second, structural model on load balancing of middleware is built and the balancing algorithm is designed to achieve the balanced of all middleware nodes and ensure the scurity and reliability of cloud services. The results of simulation show that the load balancing mechanism can achieve the balanced of middleware in cloud computing environment effectively.
