【摘要】：云計算是一種新型的資源利用和服務(wù)提供模式，它通過虛擬化和分布式技術(shù)集中管理和維護由大量計算機構(gòu)成的資源池通過網(wǎng)絡(luò)按需的向用戶提供服務(wù)，如計算、存儲空間和信息服務(wù)。我們把這些資源池形象地比喻為“云”�！霸啤蓖ǔＪ且恍┯稍朴嬎愎芾硐到y(tǒng)來進(jìn)行維護和管理的虛擬資源，包括計算服務(wù)器、存儲服務(wù)器和網(wǎng)絡(luò)寬帶資源等。云計算管理系統(tǒng)通過一定的結(jié)構(gòu)和管理策略對這些虛擬資源進(jìn)行集中管理。云計算的基本功能是通過各種接口提供對大規(guī)模數(shù)據(jù)和計算資源的訪問。 作為智能計算與云計算實驗室，我們需要了解和掌握云計算核心技術(shù)實現(xiàn)，將云計算和實驗室現(xiàn)有的智能算法結(jié)合起來，達(dá)到充分利用實驗室系統(tǒng)資源，。由于現(xiàn)有的商用云平臺大多為非開源軟件，不能滿足實驗室教學(xué)和科研的需求，所以迫切需要研發(fā)自主知識產(chǎn)權(quán)的云平臺。 在我們對開源云平臺使用和研究的過程中，逐步了解了開源云平臺OpenStack、Eucalyptus的設(shè)計理念（其設(shè)計理念同亞馬遜EC2非常相似且接口兼容），并對其網(wǎng)絡(luò)結(jié)構(gòu)進(jìn)行了深入的分析，給出了基于虛擬機鏡像注入技術(shù)的新型IP地址分配技術(shù)，并對其單一的輪詢主機分配方式進(jìn)行了改進(jìn)，提出了動態(tài)隊列主機分配方式。鑒于分布式計算已經(jīng)成為云平臺的下一步研究方向，我們準(zhǔn)備在系統(tǒng)中引入動態(tài)可伸縮的分布式計算的云技術(shù)實現(xiàn)。 本文中，我們結(jié)合開源云平臺OpenStack、Eucalyptus分析了目前主流的商用云計算平臺AMAEC2和Google的分布式計算平臺的設(shè)計理念，并基于現(xiàn)有的開源虛擬化方案KVM和分布式計算平臺Hadoop設(shè)計并實現(xiàn)了自己的AppleCloud云計算平臺，實現(xiàn)了IaaS層虛擬化資源（包括虛擬CPU、內(nèi)存、硬盤、網(wǎng)絡(luò)）的管理功能；系統(tǒng)采用了流行的模塊化設(shè)計方法，使得系統(tǒng)具有靈活的的可擴展性；系統(tǒng)使用了業(yè)界主流的云計算開發(fā)庫Libvirt進(jìn)行開發(fā)，能夠兼容目前大部分主流的虛擬化平臺，包括KVM、Xen、VMWare、VirtualBox等；本文還創(chuàng)新性的引入了基于虛擬機鏡像注入技術(shù)作為新型的云計算虛擬鏡像IP地址分配技術(shù)，與傳統(tǒng)的云計算系統(tǒng)動態(tài)IP地址分配技術(shù)，它使得云計算系統(tǒng)網(wǎng)絡(luò)結(jié)構(gòu)大為精簡優(yōu)化，對于專用的私有云而言，由于去掉了NAT網(wǎng)絡(luò)地址轉(zhuǎn)換機制，解決了傳統(tǒng)網(wǎng)絡(luò)管理機制所帶來的網(wǎng)絡(luò)瓶頸問題。但是另一方面，由于注入機制本身簡單直接，如何安全有效的利用需要進(jìn)一步的研究和探討，另外相比與傳統(tǒng)的IP地址分配機制，基于虛擬機鏡像注入技術(shù)的IP地址分配技術(shù)在地址分配技術(shù)與具體的AMI鏡像的結(jié)構(gòu)相關(guān)，需要用戶具有更高的AMI鏡像的制作能力。根據(jù)基于虛擬機鏡像注入機制的技術(shù)，我們提出并實現(xiàn)了云計算平臺上的可視化服務(wù)部署機制，用戶可以在申請?zhí)摂M機的同時選擇需要部署在上面的服務(wù)，達(dá)到即時申請即時服務(wù)的效果，不需要再去定制自己的AMI鏡像，，節(jié)省了時間，簡化了服務(wù)部署流程，提高了服務(wù)部署的靈活度。
[Abstract]:Cloud computing is a new model of resource utilization and service providing. It manages and maintains a resource pool made up of a large number of computers through the virtualization and distribution technology to provide services to users on the network, such as computing, storage space and information services. It is often the virtual resource that is maintained and managed by the cloud computing management system, including the computing server, the storage server and the network broadband resources. The cloud computing management system manages these virtual resources through a certain structure and management strategy. The basic function of the cloud computing is to provide the large scale through various interfaces. Access to data and computing resources.
As the intelligent computing and Cloud Computing Laboratory, we need to understand and master the core technology of cloud computing, and combine the existing intelligent algorithms in the laboratory to make full use of the resources of the laboratory system. Since the existing Shang Yongyun platform is mostly non source software, it can not meet the needs of laboratory teaching and scientific research. Cloud platform with independent intellectual property rights is urgently needed.
In the process of using and studying open source cloud platform, we gradually understand the design concept of open source cloud platform OpenStack, Eucalyptus (its design concept is very similar to Amazon EC2 and interface compatibility), and its network structure is deeply analyzed, and a new IP address allocation technology based on virtual machine image injection technology is given. With the improvement of the single polling host allocation method, the dynamic queuing host allocation method is proposed. In view of the distributed computing has become the next research direction of the cloud platform, we are ready to introduce the dynamic and scalable distributed computing cloud technology into the system.
In this paper, we combine the open source cloud platform OpenStack, Eucalyptus analysis of the current mainstream commercial cloud computing platform AMAEC2 and Google distributed computing platform design concept, and based on the existing open source virtualization scheme KVM and distributed computing platform Hadoop design and implementation of their own AppleCloud cloud computing platform, the implementation of the IaaS layer The management functions of virtualized resources (including virtual CPU, memory, hard disk, network); the system has adopted a popular modular design method to make the system flexible and extensible; the system is developed by the mainstream cloud computing library Libvirt in the industry, and can accommodate most of the current mainstream virtualization platforms, including KVM, Xen, VMW Are, VirtualBox and so on; this article also introduces the innovative virtual machine image injection technology as the new cloud computing virtual image IP address allocation technology, and the traditional cloud computing system dynamic IP address allocation technology, which makes the cloud computing system network structure greatly streamlined optimization, for the private private cloud, because of the removal of the NAT The network address conversion mechanism solves the problem of network bottleneck caused by the traditional network management mechanism, but on the other hand, because the injection mechanism itself is simple and direct, it needs further research and Discussion on how to use it safely and effectively. In addition, the IP address based on the virtual machine image injection technology is compared with the traditional IP address dispenser system. The matching technology is related to the structure of the address distribution technology and the specific AMI image. It requires the user to have the ability to make a higher AMI image. Based on the technology based on the virtual machine image injection mechanism, we propose and implement a visualization service deployment mechanism on the cloud computing platform. In the above service, the effect of instant application for instant service is achieved. It does not need to customize your own AMI image again, save time, simplify the service deployment process, and improve the flexibility of service deployment.
