Abstract

Abstract Cloud computing is a system development method based on dynamic sharing, which allows a large number of systems to be combined to provide services. The purpose of this work is to study the design and implementation of a dynamic virtual resource allocation system in cloud computing, whose architecture allows load balancing between virtual resource pools and reduces resource wastage. Using the cluster network topology, the resource usage of the dynamic system cluster can be monitored in real time, and the total cluster load can be automatically determined based on the monitoring data. The experiment is divided into two parts. Performance testing and scenario testing. Performance tests examine execution time, processor, and memory performance. In the scenario test, JMeter is used to simulate the occurrence of a large number of concurrent application access requests, the loss rate, and processing time of these requests on the cloud platform, and load balancing tests are performed. The test results show that the system running time is about 22–27 ms, the CPU utilization is about 90–95%, and the RAM is about 3.5 ms. The results show that cloud technology can improve resource scheduling of large tasks and optimize resource load balance.

基于系统架构的云计算虚拟资源动态系统分配与应用

云计算是一种基于动态共享的系统开发方法，它允许大量的系统组合起来提供服务。本工作的目的是研究云计算中动态虚拟资源分配系统的设计与实现，该系统的架构允许虚拟资源池之间的负载均衡，减少资源浪费。通过集群网络拓扑，可以实时监控动态系统集群的资源使用情况，并根据监控数据自动确定集群的总负载。实验分为两个部分。性能测试和场景测试。性能测试检查执行时间、处理器和内存性能。在场景测试中，使用JMeter模拟大量并发应用访问请求在云平台上的发生情况、丢失率和处理时间，并进行负载均衡测试。测试结果表明，系统运行时间约为22-27 ms, CPU利用率约为90-95%，RAM约为3.5 ms。结果表明，云技术可以改善大型任务的资源调度，优化资源负载平衡。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
