【摘要】：隨著計(jì)算機(jī)硬件性能提升,物理基礎(chǔ)設(shè)施性能冗余度不斷提高,Web服務(wù)平臺(tái)資源出現(xiàn)高成本,低利用率的問(wèn)題,傳統(tǒng)Web服務(wù)平臺(tái)的發(fā)展遇到了瓶頸。本課題通過(guò)構(gòu)建虛擬化Web服務(wù)平臺(tái)提高物理基礎(chǔ)設(shè)施資源利用率以及Web服務(wù)的可靠性和安全性,對(duì)資源進(jìn)行合理地統(tǒng)籌規(guī)劃。 本課題基于虛擬化平臺(tái)構(gòu)建技術(shù),在參考了大量國(guó)內(nèi)外相關(guān)文獻(xiàn)后,首先對(duì)對(duì)相關(guān)技術(shù)作出多角度的闡述,包括虛擬化技術(shù)產(chǎn)生的背景、發(fā)展和優(yōu)勢(shì),虛擬化負(fù)載均衡和高可用性的原理和特點(diǎn),并對(duì)VMware的虛擬化組件功能做了介紹。 其次對(duì)當(dāng)前Web服務(wù)平臺(tái)存在的問(wèn)題和構(gòu)建需求進(jìn)行了分析,進(jìn)而提出虛擬化Web服務(wù)平臺(tái)的構(gòu)建方案。根據(jù)虛擬化技術(shù)應(yīng)用領(lǐng)域的不同,虛擬化技術(shù)分為服務(wù)器虛擬化、網(wǎng)絡(luò)虛擬化和存儲(chǔ)虛擬化三個(gè)方面。通過(guò)實(shí)施具體的構(gòu)建方案提升數(shù)據(jù)中心的可擴(kuò)展性、高可用性,實(shí)現(xiàn)負(fù)載均衡。 最后研究了單點(diǎn)登錄系統(tǒng)的運(yùn)行原理,將開源單點(diǎn)登錄系統(tǒng)部署到虛擬化平臺(tái)進(jìn)行系統(tǒng)性能分析和可用性評(píng)估。分析結(jié)果表明,虛擬化Web服務(wù)平臺(tái)滿足了需求分析中提出的應(yīng)用要求。
[Abstract]:With the improvement of computer hardware performance and the improvement of physical infrastructure redundancy, the problems of high cost and low utilization of Web service platform resources have been encountered, and the development of traditional Web service platform has encountered a bottleneck. By constructing a virtualized Web service platform to improve the utilization of physical infrastructure resources and the reliability and security of Web services, this paper makes a reasonable overall planning of resources. This topic based on virtualization platform construction technology, after referring to a large number of domestic and foreign related literature, first of all, the related technologies are elaborated from various angles, including the background, development and advantages of virtualization technology. The principle and characteristics of virtualization load balancing and high availability are introduced, and the virtualization component function of VMware is introduced. Secondly, the problems and construction requirements of current Web service platform are analyzed, and then the construction scheme of virtualized Web service platform is put forward. According to the application of virtualization technology, virtualization technology can be divided into three aspects: server virtualization, network virtualization and storage virtualization. Through the implementation of specific construction scheme to enhance the data center scalability, high availability, load balancing. Finally, the principle of single sign-on system is studied, and the open source single sign-on system is deployed to the virtualization platform for system performance analysis and usability evaluation. The analysis results show that the virtualized Web services platform meets the requirements of requirements analysis.
