【摘要】：云計算技術作為第四次信息技術革命的標志,作為一種全新的計算模型和網絡應用模式,正在逐漸改變著我們的生活。圖書館作為信息資源的聚集地,隨著應用和系統(tǒng)的不斷增加,以及規(guī)模和用戶需求的多樣化,不僅帶來投入的大量增加,而且也因為更新速度比較快,圖書館的技術力量越來越顯得不足。如何在圖書館中利用云計算技術,解決圖書館面臨的問題,成為圖書館關注的一大熱點。 當前,大多數(shù)圖書館在云計算方面,僅僅限于研究,還沒有得到實際的應用。作者基于對Eucalyptus開源云平臺、虛擬機調度算法、網絡、HDFS技術等的研究,提出了數(shù)字圖書館私有云平臺的架構,并對該架構進行了詳細說明,然后根據(jù)架構的服務層次,選取了基礎設施架構、外部存儲、應用監(jiān)控系統(tǒng)等進行了詳細介紹。 首先介紹了構建數(shù)字圖書館私有云平臺基礎設施架構中所依賴的計算、操作系統(tǒng)池等的理論和實現(xiàn)過程,以及構建了用于圖書館數(shù)據(jù)存儲和共享的外部存儲環(huán)境,然后利用開源Eucalyptus平臺,搭建了數(shù)字圖書館私有云基礎設施,并和外部存儲集成,構建成為統(tǒng)一的DLCloud云基礎設施,并進行了相應的測試,接著并利用Euca2ools中間件技術,用GridSphere門戶系統(tǒng)來管理和操作DLCloud云基礎設施。同時在基于圖書館多應用的基礎上,設計與實現(xiàn)了應用監(jiān)控系統(tǒng)。最后選取了圖書館的典型應用,例如CAS認證系統(tǒng)、資源加工系統(tǒng)等,部署在該數(shù)字圖書館私有云平臺中運行,進行了穩(wěn)定性、性能、功能等的測試。 文章最后,對數(shù)字圖書館私有云平臺進行了總結,并對下一步研究工作提出了建議。
[Abstract]:Cloud computing technology, as the symbol of the fourth information technology revolution, as a new computing model and network application model, is gradually changing our lives. As a gathering place of information resources, with the continuous increase of applications and systems, and the diversification of scale and user needs, the library not only brings a large increase in investment, but also because of the relatively rapid pace of renewal. The technical power of the library is becoming more and more inadequate. How to use cloud computing technology in libraries to solve the problems faced by libraries has become a hot topic. At present, most libraries in cloud computing, only limited to research, has not been practical applications. Based on the research of Eucalyptus open source cloud platform, virtual machine scheduling algorithm and network HDFS technology, the author puts forward the architecture of private cloud platform of digital library, and explains the architecture in detail, and then according to the service level of the architecture, the author proposes the architecture of private cloud platform of digital library. The infrastructure architecture, external storage and application monitoring system are introduced in detail. This paper first introduces the theory and implementation process of computing, operating system pool, and the external storage environment for library data storage and sharing, which are relied on in the construction of private cloud platform infrastructure of digital library. Then, the private cloud infrastructure of digital library is built using open source Eucalyptus platform, and integrated with external storage, it is built into a unified DLCloud cloud infrastructure, and the corresponding test is carried out, and then the middleware technology of Euca2ools is used. Use the GridSphere portal system to manage and operate the DLCloud cloud infrastructure. At the same time, the application monitoring system is designed and implemented on the basis of library multi-application. Finally, the typical applications of the library, such as CAS authentication system, resource processing system, etc., are selected to run on the private cloud platform of the digital library, and the stability, performance and function are tested. Finally, this paper summarizes the private cloud platform of digital library and puts forward some suggestions for further research.
