【摘要】：云计算技术作为第四次信息技术革命的标志,作为一种全新的计算模型和网络应用模式,正在逐渐改变着我们的生活。图书馆作为信息资源的聚集地,随着应用和系统的不断增加,以及规模和用户需求的多样化,不仅带来投入的大量增加,而且也因为更新速度比较快,图书馆的技术力量越来越显得不足。如何在图书馆中利用云计算技术,解决图书馆面临的问题,成为图书馆关注的一大热点。当前,大多数图书馆在云计算方面,仅仅限于研究,还没有得到实际的应用。作者基于对Eucalyptus开源云平台、虚拟机调度算法、网络、HDFS技术等的研究,提出了数字图书馆私有云平台的架构,并对该架构进行了详细说明,然后根据架构的服务层次,选取了基础设施架构、外部存储、应用监控系统等进行了详细介绍。首先介绍了构建数字图书馆私有云平台基础设施架构中所依赖的计算、操作系统池等的理论和实现过程,以及构建了用于图书馆数据存储和共享的外部存储环境,然后利用开源Eucalyptus平台,搭建了数字图书馆私有云基础设施,并和外部存储集成,构建成为统一的DLCloud云基础设施,并进行了相应的测试,接着并利用Euca2ools中间件技术,用GridSphere门户系统来管理和操作DLCloud云基础设施。同时在基于图书馆多应用的基础上,设计与实现了应用监控系统。最后选取了图书馆的典型应用,例如CAS认证系统、资源加工系统等,部署在该数字图书馆私有云平台中运行,进行了稳定性、性能、功能等的测试。文章最后,对数字图书馆私有云平台进行了总结,并对下一步研究工作提出了建议。
[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.
