September 2009 Academic Library Society of China organized by the Committee \With the development of the library, more and more scholars began to focus on the concept of cloud computing business implantable digital library. 1990s, network technology breakthrough, the formation of the digital information environment, globalization, digital library construction boom, Library Services consciousness highlights, gave birth to a new digital library form of cloud services. Emergence of cloud computing will enable continuation of the previous century transition takes the form of library services. Cloud computing technology has greatly enriched the theory of library science, and the new extension and extension of library practice field. Cloud computing in the domestic book intelligence community has been a great concern, cloud computing has become a model for grid computing can not be ignored and business computing environment. At present, China Academic Library System (China Academic Library Information System, CALIS) technology center developed to support distributed digital library CALIS cloud services cloud service platform has been initially completed, the new generation of digital library systems development and implementation of lay a new technology base. Cloud computing technology will become a new bright spot in digital library services. However, an overview of domestic cloud computing digital library research and development situation, the domestic development of digital libraries and their foreign counterparts there is a big gap, both for technical reasons, there are institutional factors. Although in recent years China's digital library industry has made remarkable achievements, but because of the lag and infrastructure aspects of the quality of employees constraints, many of our lower level of digital library services, has mostly cloud-based library the project has yet to start. On the domestic digital library, the current does not have a formal cloud computing services. Analysis of the reasons, think a solution, attempts to cloud service development of digital libraries and digital libraries play a role in promoting this is the object of this paper and direction. In this paper, the development of cloud computing at home and abroad, and the starting point for the study of Research, the main contents are as follows: Chapter 1, Introduction. An overview of the research background papers, as well as the purpose and significance of research, 'and describes the current development of domestic and international cloud computing and cloud computing in the digital library research. Chapter 2, cloud computing related theory and key technology overview. Associated with the thesis on the theory are reviewed, discussed the concept of cloud computing, cloud characteristics, cloud computing architecture, cloud computing and other computing relationships and its implementation mechanisms. Chapter 3, cloud computing analysis on the impact of digital libraries. Main analysis of cloud computing impact on digital libraries. First, explain cloud computing in a digital library of value; Second, analysis of the current development of digital libraries are facing problems; Again, the analysis of cloud computing digital library functional advantages; Finally, the importance of cloud-based digital library Museum construction has certain risks need to be cautious. Chapter 4, cloud-based digital library implementation methods and strategies. Discuss cloud-based digital library practice methods and strategies. First, from the logical level of the feasibility of its implementation, and analysis of specific cloud computing digital library architecture; then expounded digital library contents and characteristics of cloud services; finally proposed the building of cloud computing digital library strategy. Chapter 5, the digital library system to build the cloud evolution. From the perspective of empirical research, the design of a virtual digital library of cloud computing resource pool configuration, database server architecture, database access mechanism, the application server architecture and network platform architecture. Further validate the implementation of cloud computing digital library feasibility and operability. Chapter 6 Conclusions and Outlook. Summarize the whole thesis on the proposed further study of the issues and prospects of cloud computing digital library development prospects. At present, the library community on digital library research cloud computing basic stay at the theoretical level and feasibility research level, the lack of a digital library system from the perspective of the entire cloud computing to study the evolution of the specific implementation. This is not only a comprehensive analysis of the current development of China's digital library of the main problems, but also through cloud computing in a digital library summed up the value of the functional advantages of cloud computing. On this basis, the design of the cloud-based digital library architecture and made a digital library to the cloud evolution strategy. This article from the perspective of empirical research, the design of a virtual digital library of cloud computing resource pool configuration, database server architecture, database access mechanism, the application server architecture and network platform architecture. Further validate the implementation of cloud computing digital library feasibility and operability. This paper focuses on the design of the system to solve the outstanding problems of digital libraries in improving the degree of virtualization, integration of information resources and resource has a unique advantage, these are also papers innovation lies. Build a successful cloud-based digital library service system is a long and arduous task, not only libraries, professionals, and has integrated computer technology talent. This gives a new era of the digital library community has brought new challenges, digital libraries only continue to attract different kinds of people for their own use, and constantly develop more convenient and readers information service model in order to reflect the core values ??of the digital library without being replaced by other industries.
