Service-Oriented Computing (SOC) is intended to improve software maintainability as businesses become more agile and underlying processes and rules change more frequently. However, to date, the impact of service cohesion on the analyzability subcharacteristic of maintainability has not been rigorously studied. Consequently, this paper extends existing notions of cohesion in the Procedural and OO paradigms in order to account for the unique characteristics of SOC, thereby supporting the derivation of design-level software metrics for objectively quantifying the degree of service cohesion. The metrics are theoretically validated, and an initial empirical evaluation using a small-scale controlled study suggests that the proposed metrics could help predict analyzability early in the Software Development Life Cycle. If future industrial studies confirm these findings, the practical applicability of such metrics is to support the development of service-oriented systems that can be analyzed, and thus maintained, more easily. In addition, such metrics could help identify design problems in existing systems. View full abstract»

In this paper, we propose a novel autonomic service delivery platform for service-oriented network environments. The platform enables a self-optimizing infrastructure that balances the goals of maximizing the business value derived from processing service requests and the optimal utilization of IT resources. We believe that our proposal is the first of its kind to integrate several well-established theoretical and practical techniques from networking, microeconomics, and service-oriented computing to form a fully distributed service delivery platform. The principal component of the platform is a utility-based cooperative service routing protocol that disseminates congestion-based prices among intermediaries to enable the dynamic routing of service requests from consumers to providers. We provide the motivation for such a platform and formally present our proposed architecture. We discuss the underlying analytical framework for the service routing protocol, as well as key methodologies which together provide a robust framework for our service delivery platform that is applicable to the next-generation of middleware and telecommunications architectures. We discuss issues regarding the fairness of service rate allocations, as well as the use of nonconcave utility functions in the service routing protocol. We also provide numerical results that demonstrate the ability of the platform to provide optimal routing of service requests. View full abstract»

Service-oriented enterprise systems, which tend to be heterogeneous, loosely coupled, long-lived, and continuously running, have to cope with frequent changes to their requirements and the environment. In order to address such changes, applications need to be inherently flexible and adaptive, supported by appropriate infrastructures. In this paper, we propose a model-driven approach for the dynamic adaptation of Web services based on ontology-aware service templates. Model-driven engineering raises the level of abstraction from concrete Web service implementations to high-level service models, which leads to more flexible and automated adaptations through template designs and transformations. The ontological semantics enhances the service matching capabilities required by the dynamic adaptation process. Service templates are based on OWL-S descriptions and provide the necessary means to capture and parameterize specific behavior patterns of service models. In this paper, we apply our approach in the context of the EU-funded ALIVE project and illustrate, as an example, how the proposed framework supports the adaptation of the authentication mechanism used by an interactive tourist recommendation system.

The Service-Oriented Architecture (SOA) approach to building systems of application and middleware components promotes the use of reusable services with a core focus of service interactions, obligations, and context. Although services technically relieve the difficulties of specific technology dependency, the difficulties in building reusable components is still prominent and a challenge to service engineers. Engineering the behavior of these services means ensuring that the interactions and obligations are correct and consistent with policies set out to guide partners in building the correct sequences of interactions to support the functions of one or more services. Hence, checking the suitability of service behavior is complex, particularly when dealing with a composition of services and concurrent interactions. How can we rigorously check implementations of service compositions? What are the semantics of service compositions? How does deployment configuration affect service composition behavior safety? To facilitate service engineers designing and implementing suitable and safe service compositions, we present in this paper an approach to consider different viewpoints of service composition behavior analysis. The contribution of the paper is threefold. First, we model service orchestration, choreography behavior, and service orchestration deployment through formal semantics applied to service behavior and configuration descriptions. Second, we define types of analysis and properties of interest for checking service models of orchestrations, choreography, and deployment. Third, we describe mechanical support by providing a comprehensive integrated workbench for the verification and validation of service compositions. View full abstract»

This paper presents an integrated service-oriented enterprise system development framework (called the BITAM-SOA Framework) as well as an instantiated design process model (called the Service Engineering Schematic) that was a result from a three-year action research case study with a Fortune 50 company in the financial services industry. The BITAM-SOA Framework and Schematic advance are both business-IT alignment and software architecture analysis techniques supporting the engineering of enterprise-wide service-oriented systems-that is, service engineering.
