【摘要】：近年來,隨著互聯(lián)網(wǎng)技術的不斷發(fā)展,基于互聯(lián)網(wǎng)技術的云計算應用越來越趨于成熟。云計算平臺能夠通過因特網(wǎng),向用戶提供廉價的、可伸縮的分布式計算能力,通過提供虛擬資源的形式向用戶提供計算資源,滿足用戶的時變的計算需求。云服務提供商(Cloud computing service providers，簡稱CCSP)按照用戶使用量收費。向用戶提供可用的、便捷的、按需的計算資源,如網(wǎng)絡,服務器,存儲,內(nèi)存,應用軟件,具體服務等。 隨著云計算用戶的不斷增加,圍繞如何在保障用戶QoS需求前提下最小化用戶使用費用的研究,這里的QoS參數(shù)包括過載率、延遲率、等待率、資源使用率等,已經(jīng)成為云計算研究中的重要研究方向。 近年來,諸多開源的云平臺不斷出現(xiàn),比如OpenNebula、Eucalyptus、 CloudStack、OpenStack等,其中以OpenStack開源云平臺的應用最為廣泛。OpenStack是一個開放源代碼的項目,是一個云平臺管理的項目。它由幾個主要的開源組件組成,這些組件共同完成云平臺的各項具體功能。OpenStack開源云平臺最顯著的特點就是能夠很好的簡化云計算平臺的部署過程,為云計算平臺帶來良好的可擴展性。 本文主要研究了云平臺中的動態(tài)資源分配問題,在總結目前已有研究成果的基礎之上,部署一個OpenStack開源云平臺,設計了一種云計算中動態(tài)資源分配策略,實現(xiàn)在保障用戶QoS需求的前提下盡可能地減少用戶使用費用的目的。
[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.
