Cloud computing is still in the stage of rapid development. So in this article the origin and concept of cloud computing will be summarized in detail, the character, basic structure of the cloud computing and its application and impact in each field will be analyzed strongly. In the cloud computing environment, the construction and service of digital library has changed greatly. The cloud storage based on digital library,the digital library infrastructure integration and construction based on cloud service, and even the library automation based on cloud computing, all of these need to research deeply in library field in the cloud computing. Besides,the changes of digital library service model based on cloud computing are also the one of the important content. In this article three kinds of service model is proposed:personalized cloud platform service model based on the needs of the users, user active push-service model and sharing cloud platform service model. Structure model is designed respectively, the working process and model of service model is explained, and their application scope is analyzed in this article.
