Transparent migration of virtual infrastructures in large datacenters for Cloud Computing.

Cloud-enabled datacenters need advanced support for an integrated management of platform virtualization technologies. The networking infrastructure of large-scale datacenters is implemented according to redundant multi-tiered architectures whose layers operate at Layer 3 of the networking stack. Splitting the network infrastructure of a datacenter in a number of IP subnets, however, creates limits to the migration of Virtual Machines, reducing the possibility for administrators to efficiently balance the load and reduce the energy consumption of the whole infrastructure.
Interconnection of geographically distributed wireless mesh testbeds: Resource sharing on a large scale.

Creating large scale testbeds for evaluating wireless mesh technologies and protocols, and for testing their ability to support real world applications in realistic environments, is a crucial step towards the ultimate success of the WMN paradigm. In this paper we suggest the hierarchical federation of a planetary scale infrastructure, such as PlanetLab, with a number of local OMF-based wireless testbeds as a viable approach towards this goal.

The success of the Cloud Computing paradigm may be jeopardized by concerns about the risk of misuse of this model aimed at conducting illegal activities. In this paper we address the issue of detecting Denial of Service attacks performed by means of resources acquired on-demand on a Cloud Computing platform. To this purpose, we propose to investigate the consequences of the use of a distributed strategy to detect and block attacks, or other malicious activities, originated by misbehaving customers of a Cloud Computing provider.

L’evoluzione delle tecnologie e delle modalità di fruizione delle stesse da parte degli utenti finali e/o grandi compagnie sta spostando la visione classica di ICT, ovvero grandi datacentre localizzati sul territorio e fruizione dei servizi erogati mediante Personal Computer.
Dynamic Virtual Cluster reconfiguration for efficient IaaS provisioning
Roberto Bifulco — Sat, 05/08/2010 - 16:49
Cloud computing is an emerging paradigm to provide Infrastructure as a Service (IaaS). In this paper we present NEPTUNE-IaaS, a software system able to support the whole lifecycle of IaaS provisioning in a Virtual Cluster environment. Our system allows interactive design of complex system topologies and their efficient mapping onto the available physical resources of a cluster. It also provides transparent VM migration features across geographically distributed datacenters, thanks to the adoption of the Service Switching paradigm.
