A file storage service on a cloud computing environment for digital libraries

Abstract

The growing need for digital libraries to manage large amounts of data requires storage infrastructure that libraries can deploy quickly and economically. Cloud computing is a new model that allows the provision of information technology (IT) resources on demand, lowering management complexity. This paper introduces a file-storage service that is implemented on a private/hybrid cloud-computing environment and is based on open-source software. The authors evaluated performance and resource consumption using several levels of data availability and fault tolerance. This service can be taken as a reference guide for IT staff wanting to build a modest cloud storage infrastructure.
