基于ESXi性能计数的Nginx负载均衡算法研究

Research on Nginx Load Balancing Algorithm Based on ESXi Performance Counter

在现有Nginx负载均衡算法的基础上,提出基于ESXi性能计数的负载均衡算法(dynamic weight based on ESXi performance counter,DWEPC),旨在通过均衡集群中的各节点负载,达到降低节点内资源过载的情况,从而提高系统性能。试验表明,相比于Nginx内置均衡算法,DWEPC算法具有更优的效果。

Based on the existing Nginx load balancing algorithm,this paper proposes a load balancing algorithm named DWEPC(dynamic weight based on ESXi performance counter),which aims to reduce the resource overload in single node by balancing the load of each node in the cluster,and improves the system performance thereby.Experiments show that the DWEPC algorithm has better results than the Nginx built-in equalization algorithm.
