Cloud computing and RESERVOIR project

The support for complex services delivery is becoming a key point in current internet technology. Current trends in internet applications are characterized by on demand delivery of ever growing amounts of content. The future internet of services will have to deliver content intensive applications to users with quality of service and security guarantees. This paper describes the RESERVOIR project and the challenge of a reliable and effective delivery of services as utilities in a commercial scenario. It starts by analyzing the needs of a future infrastructure provider and introducing the key concept of a service oriented architecture that combines virtualisation-aware grid with grid-aware virtualisation, while being driven by business service management. This article will then focus on the benefits and the innovations derived from the RESERVOIR approach. Eventually, a high level view of RESERVOIR general architecture is illustrated

Mitigating security threats to large-scale cross border virtualization infrastructures

Cloud Computing is being a computation resources platform where it is possible to make up an environment flexible and scalable able to host any kind of services. In Cloud Computing, virtualization technologies provide all the needful capabilities to deploy services and run applications in an easy way. Furthermore, large-scale cross border virtualization infrastructures present promising landscape to cope with the ever increasing requirements of modern scientific and business applications. The large-scale cross border virtualization infrastructures can be seen as a federation of heterogeneous clouds. We present pragmatic analysis of the potential threats posed to the emerging large-scale cross border virtualization infrastructures. We have taken into consideration both internal and external threats to these infrastructures. We also drive the discussion considering a real model of cloud. In particular an infrastructure cloud is briefly presented; a useful scenario where to assess security threats and apply security solutions, that is the European Project, RESERVOIR

TEFIS: a single access point for conducting multifaceted experiments on heterogeneous test facilities

A few years ago, an experimental facility composed of networking gear and simulation tools was sufficient for testing the main features of a prototype before the final product could be launched to the Internet market. This paradigm has certainly changed, but the lack of platforms enabling the realistic assessment of the different facets of a product, including cross-cutting trials across different testbeds, poses strong limitations for researchers and developers. In light of this, we present an open platform that offers a versatile combination of heterogeneous experimental facilities called “TEstbed for Future Internet Services” (TEFIS). TEFIS provides a single access point for conducting cutting-edge experiments on testbeds that supply different capabilities, including testbeds dedicated to network performance, software performance, grid computing, and living labs. We shall show that TEFIS covers the entire life-cycle of a multifaceted experiment, with the advantage that a single testrun can seamlessly execute across different experimental facilities. In order to demonstrate the potential and versatility of the TEFIS platform, we describe the deployment of four distinct experiments and provide a set of results highlighting the benefits of using TEFIS. The experiments described in this article cover: (i) the experimentation with an open API called OPENER (which is an open and programmable environment for managing experimentation with SDN applications); (ii) an application for skiers and tourists at the Megève ski resort in France; (iii) an application that can dynamically adapt the Quality of Experience (QoE) of multimedia services for mobile users; and (iv) an augmented reality workspace for remote education and learning purposes based on videoconferencing.Peer ReviewedPostprint (published version
