Design and Implementation of an XML-based Grid File Storage System with Security Features
Most of scientific computations are performed on the grid which addresses the always increasing demand for computational and storage power offering an infrastructure, available to the scientists 24 hours-a-day, by means of a specific middleware that hides much of the complexity. Grid computing is currently shifting toward a new processing model known as business services. The use of grid technology, in fact, allows business companies to achieve an higher productivity, to decrease maintenance costs and to adapt to market demands with an increased customer satisfaction. To meet these challenges, grid computing needs to address several issues in term of Quality of Service (QoS), service accountability and security.
