【摘要】：近年来,随着互联网技术的不断发展,基于互联网技术的云计算应用越来越趋于成熟。云计算平台能够通过因特网,向用户提供廉价的、可伸缩的分布式计算能力,通过提供虚拟资源的形式向用户提供计算资源,满足用户的时变的计算需求。云服务提供商(Cloud computing service providers，简称CCSP)按照用户使用量收费。向用户提供可用的、便捷的、按需的计算资源,如网络,服务器,存储,内存,应用软件,具体服务等。 随着云计算用户的不断增加,围绕如何在保障用户QoS需求前提下最小化用户使用费用的研究,这里的QoS参数包括过载率、延迟率、等待率、资源使用率等,已经成为云计算研究中的重要研究方向。 近年来,诸多开源的云平台不断出现,比如OpenNebula、Eucalyptus、 CloudStack、OpenStack等,其中以OpenStack开源云平台的应用最为广泛。OpenStack是一个开放源代码的项目,是一个云平台管理的项目。它由几个主要的开源组件组成,这些组件共同完成云平台的各项具体功能。OpenStack开源云平台最显著的特点就是能够很好的简化云计算平台的部署过程,为云计算平台带来良好的可扩展性。 本文主要研究了云平台中的动态资源分配问题,在总结目前已有研究成果的基础之上,部署一个OpenStack开源云平台,设计了一种云计算中动态资源分配策略,实现在保障用户QoS需求的前提下尽可能地减少用户使用费用的目的。
[Abstract]:In recent years, with the continuous development of Internet technology, cloud computing applications based on Internet technology are becoming more and more mature. Cloud computing platform can provide users with cheap scalable distributed computing power through the Internet and provide users with computing resources in the form of virtual resources to meet the time-varying computing needs of users. Cloud service provider (Cloud computing service providers, acronyms CCSP) charge according to user usage. Provide users with available, convenient, on-demand computing resources such as network, server, storage, memory, application software, specific services, etc. With the increasing number of cloud computing users, the research on how to minimize the cost of user use under the premise of protecting the user's QoS requirements is focused on. The QoS parameters here include overload rate, delay rate, waiting rate, resource utilization rate, etc. Cloud computing has become an important research direction. In recent years, many open source cloud platforms have been emerging, such as OpenNebula,Eucalyptus, CloudStack,OpenStack, among which OpenStack is the most widely used cloud platform. OpenStack is an open source project and a cloud platform management project. It consists of several major open source components that work together to complete the specific features of the cloud platform. The most significant feature of the OpenStack open source cloud platform is its ability to simplify the deployment process of the cloud computing platform. For cloud computing platform to bring good scalability. This paper mainly studies the dynamic resource allocation problem in cloud platform. On the basis of summarizing the existing research results, we deploy a OpenStack open source cloud platform and design a dynamic resource allocation strategy in cloud computing. The purpose is to reduce the cost of QoS as much as possible on the premise of protecting the user's QoS requirements.
