| 摘 要： | 针对云环境下大量并行计算易导致节点负载不均影响云平台服务质量的问题，提出一种基于云环境的弹性负载均衡方案。该方案构造了负载均衡模型框架，对虚拟机负载状况和虚拟机集群资源利用率进行量化评估，并为实现虚拟机集群负载的均衡和弹性伸缩，设计了负载均衡模型和弹性伸缩算法。测试结果表明在该负载均衡机制下，新方案的用户响应时间有所改善，可相应提高资源利用率。

| Abstract: | A large number of parallel computing can cause node crash under the cloud environ- ment, and therefore affect the quality of the cloud platform services. A load balancing scheme based on elastic cloud environment is proposed in this paper. A model of load balancing frame- work for virtual machines is constructed in this scheme so that load condition and the virtual ma- chine cluster resource utilization can be evaluated. A load balancing model and elastic expansion algorithm are also designed for the flexible implementation of load balancing and the virtual ma- chine cluster. Test results show that user response time is decreased, and the utilization rate of resources is improved by using this load balancing mechanism. |
