【摘要】：云計(jì)算技術(shù)的出現(xiàn)引發(fā)了IT領(lǐng)域的重大變革,它不僅改變了IT公司交付軟件和硬件產(chǎn)品的模式,也影響了用戶通過互聯(lián)網(wǎng)存儲和獲取信息的方式。云計(jì)算技術(shù)憑借其自身巨大的優(yōu)勢,吸引了眾多的服務(wù)提供商將應(yīng)用服務(wù)部署到云上。在業(yè)務(wù)云平臺上,資源分配的效率將直接影響到服務(wù)運(yùn)行的性能和成本,是業(yè)務(wù)云平臺商業(yè)化過程中必須解決的一個(gè)關(guān)鍵問題。因此,研究在業(yè)務(wù)云平臺上如何進(jìn)行高效的資源分配具有重要的研究意義和應(yīng)用價(jià)值。 為此,我們學(xué)習(xí)和了解了與云計(jì)算相關(guān)的基礎(chǔ)知識和關(guān)鍵技術(shù),并比較了當(dāng)前幾種常見的開源IaaS云平臺。根據(jù)各個(gè)平臺的特點(diǎn)及本研究的實(shí)際需求,選取了OpenStack開源項(xiàng)目用于構(gòu)建私有業(yè)務(wù)云平臺,并將多媒體分享業(yè)務(wù)部署到該平臺上。在學(xué)習(xí)了云計(jì)算環(huán)境中幾種常見的分配算法后,本論文對業(yè)務(wù)云平臺上的資源分配問題進(jìn)行了分析和建模,根據(jù)業(yè)務(wù)云平臺的特點(diǎn)提出了一個(gè)資源分配模型,并將其實(shí)現(xiàn)。分配模型分為兩級：物理機(jī)級別和虛擬機(jī)級別。在物理機(jī)級別,選用OpenStack項(xiàng)目的簡單分配算法為各個(gè)虛擬實(shí)例分配平臺中的物理資源；在虛擬機(jī)級別,將問題看作是尺寸可變的裝箱問題,提出一種算法來實(shí)現(xiàn)以服務(wù)組件為單位的資源分配。 經(jīng)實(shí)驗(yàn)驗(yàn)證,提出的資源分配模型在業(yè)務(wù)云平臺上實(shí)現(xiàn)了預(yù)期的分配效果。分配結(jié)果可以保證滿足服務(wù)性能的要求,同時(shí)還可以減少一些額外開銷,使資源的利用更加有效。
[Abstract]:The emergence of cloud computing technology has triggered a major change in the field of IT. It has not only changed the mode of delivering software and hardware products by IT, but also affected the way users store and obtain information through the Internet. Cloud computing technology has attracted many service providers to deploy application services to the cloud because of its huge advantages. On the business cloud platform, the efficiency of resource allocation will directly affect the performance and cost of service operation, and it is a key problem that must be solved in the process of commercialization of business cloud platform. Therefore, it is of great significance and application value to study how to allocate resources efficiently on business cloud platform. For this reason, we have learned and learned the basic knowledge and key technologies related to cloud computing, and compared several common open source IaaS cloud platforms. According to the characteristics of each platform and the actual requirements of this study, the OpenStack open source project is selected to build a private business cloud platform, and the multimedia sharing service is deployed to the platform. After learning several common allocation algorithms in cloud computing environment, this paper analyzes and models the resource allocation problem on business cloud platform, and proposes a resource allocation model according to the characteristics of business cloud platform, and implements it. The allocation model is divided into two levels: physical machine level and virtual machine level. At the physical machine level, the simple allocation algorithm of OpenStack project is selected to allocate the physical resources in the platform for each virtual instance. At the virtual machine level, the problem is regarded as a packing problem with variable size, and an algorithm is proposed to realize the resource allocation in the unit of service components. The experimental results show that the proposed resource allocation model achieves the expected allocation effect on the business cloud platform. The allocation results can meet the requirements of service performance, but also reduce some additional overhead, so that the utilization of resources can be more effective.
