Cloud federation paradigm can help cloud providers (CPs) to overcome resource limitation during spikes in demand, by outsourcing requests to other CPs with idle resources in federation. In this paper, we consider a broker-based market where multiple CPs compete to lease multiple CPs with idle resources for request outsourcing. We propose an iterative double auction mechanism that ensures the efficient...
Media traffic has become the major traffic of the Internet and will keep on increasing. Numerous storage services, media applications and devices have emerged to provide Internet enabled content storage and delivery capabilities. Content Delivery Networks (CDN) based on cloud storage, adopting distributed storage technology in the edge servers, enable efficient data storage and retrieval system that...
Cloud computing is an emerging paradigm in which tasks are assigned to a combination (“cloud”) of servers and devices, accessed over a network. Typically, the cloud constitutes an additional means of computation and a user can perform workload factoring, i.e., split its load between the cloud and its other resources. Based on empirical data, we demonstrate that there is an intrinsic relation between...
It is clear that Cloud computing is and will be a sea change for the Information Technology by changing the way in which both software and hardware are designed and purchased. In this work we address the use of this emerging computing paradigm into web hosting providers in order to avoid its resource management limitations. Thanks to the Cloud approach, resources can be provided in a dynamic way according...
