Monitoring activities detect changes in the environment and can be used for several purpose. To develop new advanced services for smart environments, data gathered during the monitoring need to be stored, processed and correlated to different pieces of information that characterize or influence the environment itself. In this paper we propose a Cloud storage solution able to store huge amount of heterogeneous...
Cloud federation is the future of the cloud computing. In such new emerging scenarios, the "hot" and "cold" migration imply the movement of a virtual machine disk-image from a server placed in a cloud provider to a server placed in another one, with a consequent consumption of bandwidth and cloud resources. This paper aims to reduce such costs proposing a Composed Image Cloning...
Cloud federation aims to cost-effective assets and resources optimization among heterogeneous environments where clouds can cooperate together with the goal of obtaining unbounded computation resources, hence new business opportunities. This paper describes an architecture for the federation establishment, where clouds that need external resources ask to federated clouds the renting of extra physical...
Cloud Computing is becoming one of the most important topics in the IT world. Several challenges are being raised from the adoption of this computational paradigm including security, privacy, and federation. This paper aims to introduce new concepts in cloud computing and security, focusing on heterogeneous and federated scenarios. We present a reference architecture able to address the Identity Management...
