【摘要】：目前,企業(yè)計(jì)算領(lǐng)域正在出現(xiàn)一種新的研究熱點(diǎn),就是云計(jì)算。這種計(jì)算模式允許用戶根據(jù)自己的需要獲取計(jì)算資源。從而當(dāng)大量的請(qǐng)求突然到來(lái)時(shí),企業(yè)能夠良好地處理并且做到按需分配。倘若一個(gè)企業(yè)按照需求的最大值分配資源來(lái)適應(yīng)隨變化的時(shí)間而大幅度變動(dòng)的計(jì)算服務(wù)請(qǐng)求,那么它必須做好巨額投入的預(yù)算。倘若它為了節(jié)省開(kāi)銷而走向另一個(gè)極端,即只分配資源的最小值,那么在突發(fā)性請(qǐng)求來(lái)臨時(shí),該企業(yè)可能面臨難以預(yù)測(cè)的可怕后果。 另一方面,云計(jì)算的發(fā)展產(chǎn)生了很多流行的開(kāi)源云計(jì)算技術(shù),OpenStack是典型的一種。OpenStack擁有商業(yè)云所具有的一切特點(diǎn),同時(shí)它還包含部署簡(jiǎn)單,易于開(kāi)發(fā)和擴(kuò)展的優(yōu)點(diǎn),特別適合于企業(yè)內(nèi)部和科研機(jī)構(gòu)搭建私有云。因此,本文基于OpenStack開(kāi)源云技術(shù),針對(duì)現(xiàn)有的一個(gè)面向移動(dòng)用戶的多媒體服務(wù)平臺(tái),進(jìn)行了業(yè)務(wù)云平臺(tái)的動(dòng)態(tài)可伸縮性研究,提出了一個(gè)分層次的云平臺(tái)模型,并實(shí)現(xiàn)了相應(yīng)的云擴(kuò)展算法。 本文首先介紹了云計(jì)算技術(shù)當(dāng)前的研究情況,然后對(duì)虛擬化技術(shù)、它與云計(jì)算的關(guān)系和云計(jì)算的分類等進(jìn)行了闡述,還對(duì)幾種開(kāi)源的IaaS云平臺(tái)進(jìn)行了比較。本文接下來(lái)簡(jiǎn)要地介紹了已有的多媒體服務(wù)平臺(tái),將它的服務(wù)進(jìn)行拆分并做了簡(jiǎn)要的解析。本文的重點(diǎn)是OpenStack云的調(diào)研,目標(biāo)是搭建一個(gè)多節(jié)點(diǎn)的OpenStack業(yè)務(wù)云平臺(tái),并基于它完成了具有高可伸縮性的云化業(yè)務(wù)執(zhí)行平臺(tái)的設(shè)計(jì)與實(shí)現(xiàn)。實(shí)驗(yàn)結(jié)果顯示,這個(gè)業(yè)務(wù)云平臺(tái)能夠?qū)崿F(xiàn)在時(shí)間限制和最小化能耗的條件下虛擬機(jī)資源的自動(dòng)擴(kuò)展機(jī)制,以保證高突發(fā)高波動(dòng)性的負(fù)載請(qǐng)求下的服務(wù)質(zhì)量并節(jié)約開(kāi)銷。
[Abstract]:At present, the enterprise computing field is emerging a new research hotspot, namely cloud computing. This computing model allows users to access computing resources according to their needs. Thus, when a large number of requests suddenly arrive, the enterprise can handle well and distribute according to demand. If an enterprise allocates the resources according to the maximum demand to adapt to the computing service request which changes greatly with the change of time, then it must make the budget of the huge investment. If it goes to the other extreme to save money, that is, to allocate only the minimum value of resources, the enterprise may face unpredictable and terrible consequences when sudden requests come. On the other hand, the development of cloud computing has produced many popular open source cloud computing technologies OpenStack is a typical. OpenStack has all the characteristics of the business cloud, but it also has the advantages of simple deployment, easy to develop and extend. Especially suitable for enterprises and scientific research institutions to build private clouds. Therefore, based on the OpenStack open source cloud technology, this paper studies the dynamic scalability of the service cloud platform for a mobile user oriented multimedia service platform, and proposes a hierarchical cloud platform model. The corresponding cloud expansion algorithm is implemented. This paper first introduces the current research situation of cloud computing technology, then describes the virtualization technology, the relationship between virtualization and cloud computing and the classification of cloud computing, and also compares several open source IaaS cloud platforms. Next, this paper briefly introduces the existing multimedia service platform, splits its services and makes a brief analysis. The focus of this paper is the research of OpenStack cloud, the goal is to build a multi-node OpenStack service cloud platform, and based on it, the design and implementation of cloud service execution platform with high scalability are completed. The experimental results show that the service cloud platform can automatically expand virtual machine resources under the condition of time limit and minimum energy consumption to ensure the quality of service under high burst and high volatility of load request and save the cost.
