Analysis of Key Technologies of Digital Library Based on Cloud Computing

With the development of information technology, the library has changed greatly, and the target of the intensive literature information resources has been seriously challenged. The existing mode of information resources has gradually changed from the analog to digital state. The digital library began to enter the era of cloud computing. Cloud computing as a suitable for the application of the library architecture model, can be dispersed digital information resources integration, the intensification of the digital library, the construction and sharing of digital resources to provide a new solution. At first, this paper analyzes the concept of cloud computing and related technology, and then introduces the needs of the construction of digital library, finally to cloud computing in the construction of digital library applications. Secondly, it discusses how to design the architecture of Digital Library Based on cloud computing technology. From the logical structure of the digital library, the digital library cloud service platform, the implementation strategy of the digital library and the operation flow of the digital library. Finally, the design and implementation of a digital library is designed, which is composed of information resource management system, platform service system, information retrieval system, information system, information distribution system and information processing system. And gives the implementation process using Google and Amazon cloud services platform.
