We will discuss on new methods and tools for building high personalized, virtual e-business services. A new service provisioning architecture based on web services has been conceived, taking into account issues related to end-user mobility. The following pages deal with a proposal for creating real localized, personalized virtual environments using web services and domain ontologies. In particular, to overcome interoperability issues that could arise from a lack of uniformity in service descriptions, we propose a way for controlling and enforcing annotation policies based on a service registration authority. It allows services to be advertised according to guidelines and domain rules. Furthermore, this solution enables enhanced service/component discovery and validation, helping software engineers to build services by composing building blocks and provision/deliver a set of personalized services.

Organizations in all sectors of business and government are pursuing service-oriented architecture (SOA) initiatives in response to their need for increased business agility. This is particularly true for mobile telecommunications companies. That is why mobile telecom operators need to research new and innovative sources of revenue. Innovation is not an easy task. It requires embracing a new way of doing business, where new technologies are fundamental. SOA architecture and Web services technology are proposed by IT industry as the best solution to create a network of partnership and new services, but despite software producer claims, interoperability issues arise with service composition. Such a problem can be significantly reduced by adopting a semantic approach in service description and service discovery.

Abstract. This article describes the architecture of sea situational awareness (SSA) platform, a major asset within TESSA, an industrial research project funded by the Italian Ministry of Education and Research. The main aim of the platform is to collect, transform and provide forecast and observational data as information suitable for delivery across a variety of channels, like web and mobile; specifically, the ability to produce and provide forecast information suitable for creating SSA-enabled applications has been a critical driving factor when designing and evolving the whole architecture. Thus, starting from functional and performance requirements, the platform architecture is described in terms of its main building blocks and flows among them: front-end components that support end-user applications and map and data analysis components that allow for serving maps and querying data. Focus is directed to key aspects and decisions about the main issues faced, like interoperability, scalability, efficiency and adaptability, but it also considers insights about future works in this and similarly related subjects. Some analysis results are also provided in order to better characterize critical issues and related solutions.

This paper describes a framework application for the control plane of a network infrastructure; the objective is to feature end-user applications with the capability of requesting at any time a customised end-to-end Quality-of-Service profile in the context of dynamic Service-Level-Agreements. Our solution targets current and future real-time applications that require tight QoS parameters, such as a guaranteed end-to-end delay bound. These applications include, but are not limited to, health-care, mobility, education, manufacturing, smart grids, gaming and much more. We discuss the issues related to the previous Integrated Service and the reason why the RSVP protocol for guaranteed QoS did not take off. Then we present a new signaling and resource reservation framework based on the cutting-edge network controller ONOS.  Moreover, the presented system foresees the need of considering the edges of the network, where terminal applications are connected to, to be piloted by distinct logically centralised controllers. We discuss a possible inter-domain communication mechanism to achieve the end-to-end QoS guarantee.

This chapter explores emerging technologies centered around cloud computing. From the technological point of view, cloud computing was born as a result of the emergence and the convergence of contemporary technologies. This chapter regards technological aspects of cloud. In the software area, Virtualization Technology and Web Services; in the hardware area, shared compute components (i.e., multicore processors); in networking, security, network virtualization, Virtual Private Network (VPN), virtual firewalls, and network overlay are the promising technologies for the future complex computing infrastructures. In this chapter, the authors review these technologies and describe how they contribute to the anatomy and the characteristics of cloud computing. These technologies constitute the building blocks of cloud computing technologies and infrastructures.

Mobile business services are attracting increasing attention and they promise a multibillion dollar market whose characteristics are quite distinct compared to mobile consumer services. Competitive activity among players keen on tapping into this opportunity is increasing rapidly. In this article, we look at mobile business services from a strategic business perspective. We chart the mobile business services landscape and discuss the underlying market drivers and potential end-user benefits. Additionally, we describe the competitive landscape and discuss the relative positions of the primary player groups.

Fusion Approach

The research project FUSION aims at supporting collaboration and interconnection between enterprises with technologies that allow for the semantic fusion of heterogeneous service-oriented business applications. The resulting FUSION approach is an enterprise application integration (EAI) conceptual framework proposing a system architecture that supports the composition of business processes using semantically annotated Web services as building blocks. The approach has been validated in the frame of three collaborative commercial proof-of-concept pilots. The chapter provides an overview on the FUSION approach and summarises our integration experiences with the application of the FUSION approach and tools during the implementation of transnational career and human resource management services.
