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. Our research is focused 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.

Service Oriented Architecture is a software design paradigm of choice for building and integrating distributed Information Systems. The greatest challenge of SOA is to make the system more flexible and adaptable to the enterprise and user environment changes. However, services can change constantly. These changes are produced due to adjustment in structure, e.g., changing service signature, integrating new services into existing business services; in behavior e.g., adding new business rules in simple or composite services; and in interaction schema between the services and the clients. This paper presents a solution based on service component concepts for dealing with changes confined to services and clients in SOA-based applications. It uses service components concepts to define adaptable services that facilitate the extension and the customization of existing services in harmony with service users. In addition, it presents an adaptation service-oriented lifecycle scenario to control service changes in the entire service lifecycle ranging from the announcement to the execution phase

Root Of Trust

Service Oriented Architecture (SOA) is an architectural paradigm that enables dynamic composition of heterogeneous, independent, multi-vendor business services. A prerequisite for such inter-organizational workflows is the establishment of trustworthiness, which is mostly achieved through non-technical measures, such as legislation, and/or social consent that businesses or organizations pledge themselves to adhere. A business process can only be trustworthy if the behavior of all services in it is trustworthy. Trusted Computing Group (TCG) has defined an open set of specifications for the establishment of trustworthiness through a hardware root-of-trust. This paper has three objectives: firstly, the behavior of individual services in a business process is formally specified. Secondly, to overcome the inherent weaknesses of trust management through software alone, a hardware root of-trust devised by the TCG, is used for the measurement of the behavior of individual services in a business process. Finally, a verification mechanism is detailed through which the trustworthiness of a business process can be verified.

Legacy Applications

In the commercial world, the value of ubiquitous computing applications is proportional to the range of business services that can be accessed in device-consumptive ways. Services originate in legacy applications of organizations, and are developed and operated typically in heterogeneous environments. Service-oriented architecture (SOA), supported by a complex stack of Web services standards, addresses ways in which software components of diverse applications can be homogeneously interacted with and composed. Thus, SOA provides a crucial mechanism for making services accessible to ubiquitous computing applications. In this chapter, we shed light on what SOA entails, based on Web services interfaces and messaging, and service composition through single-party process orchestration and multiparty choreography languages. For the latter, concrete patterns are used to describe the capabilities of prospective standards. Ways in which SOA needs be extended to allow wider and more flexible service trading, typified in current developments through service marketplaces, are then discussed. Such extensions, we argue, converge with directions in ubiquitous computing through so-called ubiquitous service networks and service ecosystems.

Since the beginning of the Service-Oriented Architecture (SOA) paradigm, with its various implementation technologies such as Web services, the focus of industrial communities has been on providing tools that would allow seamless and flexible application integration within and across enterprises’ boundaries. In this paper, the authors present a Context-based, Service-oriented Modeling and Analysis (CSMA) method that guides service engineers in their choices of identifying, defining, and analyzing adaptable business services. The proposed method is business centric and comprises a set of structured steps grouped in two phases. Besides, the CSMA embraces Model-Driven Architecture (MDA) principles to model and refine adaptable business services models in the PIM level. The results from a pilot validation of CSMA for SOA enablement of a realistic enterprise training solutions are also presented.

Business Interoperability

Service Oriented Architecture (SOA) is gaining acceptance, offering advantages including closer alignment of IT systems with business. Ideally, within large enterprises, capabilities would be used by solutions from a number of business units while matching the detailed requirements of each; this level of interoperability is difficult to achieve. While much of the current activity focuses on technical interoperability we propose that the focus shift to business interoperability as the key consideration to bring clarity to the engineering aspects of technical interoperability. A model-driven architectural approach is presented that views an organisation’s business processes as structured assets requiring formalisation. A new concept is presented, the conceptual business service (CBS), which provides abstraction through modeling, and promotes building a portfolio of navigable business services at the appropriate level of abstraction and granularity. A method for specifying a CBS is outlined using reference domain meta-data allowing easier service solution recognition among other benefits.
