	abstract = {<p>This paper deals with Cloud federation issues, where Clouds are both providers and clients of virtual resource at the same time. Specifically, we have designed a solution based on a XMPP communication platform, which allows to set up federated environments and to easily manage virtual shared resources. Heterogeneous and dynamic Clouds can interact in near-real time, making available their own resources according to specific agreement policies. We are thinking to implement the proposed solution using the Hadoop framework, a well-known Cloud Map-Reduce middleware designed to offer different types of services. Here, we analyze the basic and useful elements necessary to making up federated clouds. By mean of Cloud federation, two or more Hadoop clusters can be connected in order to increase service scalability, overcoming some technical limitations of the Hadoop framework itself.</p>

	abstract = {<p>Nowadays, in the panorama of Cloud Computing, finding a right compromise between interactivity and security is not trivial at all. Currently, most of Cloud providers base their communication systems on the web service technology. The problem is that both Cloud architectures and services have started as simple but they are becoming increasingly complex. Consequently, web services are often inappropriate. Recently, many operators in both academia and industry are evaluating the eXtensible Messaging and Presence Protocol for the implementation of Cloud communication systems. In fact, the XMPP offers many advantages in term of real-time capabilities, efficient data distribution, service discovery, and inter-domain communication compared to web service technologies. Nevertheless, the protocol lacks of native security features. In this paper, we explore such security issues, discussing how they can be mitigated using both SAML/SASL Single Sign-On (SSO) and XEP 0027.</p>
