CLOUD COMPUTING: AN EMERGING TECHNOLOGY

Now a day’s maintenance of infrastructure for Web based digital library faces several challenges. It has attained the full fledge status. Libraries may soon be building and managing their own data centers. This model would be helpful for the libraries to maintain and more control over the applications and data stores that contain sensitive, private information about patrons. This paper highlights the problems faced with digital library and developmental efforts to overcome those problems. Infrastructure virtualization and cloud computing are particularly attractive choices which is challenged by both growth in the size of the indexed document collection, new features and most prominently usage. Cloud Computing is applying or to be a part of university library, the paper also describes the current status of user service models in university libraries. Then it proposed to improve current user service model with Cloud Computing. Some issues like data location, mobility and availability also discuss in this paper
