Service-Oriented Architectures (SOA) enable the automatic creation of business applications from independently developed and deployed Web services. As Web services are inherently a priori unknown, how to deliver reliable Web services compositions is a significant and challenging problem. Services involved in an SOA often do not operate under a single processing environment and need to communicate using different protocols over a network. Under such conditions, designing a fault management system that is both efficient and extensible is a challenging task. In this article, we propose SFSS, a self-healing framework for SOA fault management. SFSS is predicting, identifying, and solving faults in SOAs. In SFSS, we identified a set of high-level exception handling strategies based on the QoS performances of different component services and the preferences articled by the service consumers. Multiple recovery plans are generated and evaluated according to the performance of the selected component services, and then we execute the best recovery plan. We assess the overall user dependence (i.e., the service is independent of other services) using the generated plan and the available invocation information of the component services. Due to the experiment results, the given technique enhances the service selection quality by choosing the services that have the highest score and betters the overall system performance. The experiment results indicate the applicability of SFSS and show improved performance in comparison to similar approaches.

Many benefits from implementation of e-business solutions are related to network effects which means that there are many interconnected parties utilizing the same or compatible technologies. The large-scale adoption of e-business practices in public sectors and in small and medium enterprises (SMEs)-prevailing economic environments will be successful if appropriate support in the form of education, adequate legislative, directions, and open source applications is provided. This case study describes the adoption of e-business in public sectors and SMEs by using an integrated open source approach called e-modules. E-module is a model which has process properties, data properties, and requirements on technology. Therefore e-module presents a holistic framework for deployment of e-business solutions and such e-module structure mandates an approach which requires reengineering of business processes and adoption of strong standardization that solves interoperability issues. E-module is based on principles of service-oriented architectures with guidelines for introduction into business processes and integration with ERP systems. Such an open source approach enables the spreading of compatible software solutions across any given country, thus, increasing e-business adoption. This paper presents a methodology for defining and building e-modules.

Technological Opportunities

Service-oriented architectures offer promising means to flexibly organize business processes. At the same time, new challenges for management arise in order to realize these potentials. Given the technological opportunities, these challenges essentially lie in choosing the right mix of services on the basis of an appropriate infrastructure supporting value adding activities. In order to support this management perspective, a focus on service-oriented business processes is suggested in this article. Hence, a shift from technical aspects of designing service-oriented information systems to economic aspects of using them according to business needs is drawn. For this purpose, findings on the evaluation of financial performance of service-oriented business processes are presented in this paper. The objective is to develop a measurement system for decision support on the con-figuration of a company’s service portfolio reflecting specific economic conditions relevant in a certain situation. Following a design science approach, general principles of a measurement system are worked out and structured in a comprehensive framework. Then, the application of a corresponding system is presented with a practical study. Finally, perspectives on the specification and implementation of the system are sketched.

Definition Of

E-Business research and practice can be situated on following multiple levels: applications, technological issues, support and implementation (Ngai and Wat 2002). Here we consider technological components for realizing business processes and discuss their foundation architecture for technological enabling. The article provides an introduction to the terms, techniques and realization issues for eventdriven and service-oriented architectures. We begin with a definition of terms and propose a reference architecture for an event-driven service-oriented architecture (EDSOA). Possible applications in the area of E-Business and solution guidelines are considered in the second part of the article. Service-oriented Architectures (SOA) have gained momentum since their introduction in the last years. Seen as an approach to integrate heterogeneous applications within an enterprise architecture they are also used to design flexible and adaptable business processes. An SOA is designed as a distributed system architecture providing a good integration possibility of already existing application systems. Furthermore, SOA is mostly suitable for complex and large system landscapes.

The Moment

The chapter “Ubiquitous Services and Business Processes” discussed the benefits for real time enterprises of service oriented architectures (SOA) in terms of reusability and flexibility. Web services are one incarnation of SOA. This chapter gives a brief introduction to SOA. It discusses the attributes that define SOA, the roles of the participants in a service oriented environment. The essence of SOA is that clients use services offered by a service provider to get a task done. For the moment we simplify service to “a software component with network connection”. Services are offered with a description at wellknown “places” (also called registries, repositories), where clients choose services according to their needs. The chapter discusses several approaches to describe services and to look for them. Moreover, some well-known systems, and also current research, are discussed.

Incremental Process

The adoption of the agile methods' principles has emerged as an effective way to develop service oriented architectures as it paves the way for a better reply to the changing needs of the environment and even the customer. However, these changes may also require the evolution of the development process itself. This paper presents an agile and service-oriented software development method that combines concepts from the Service-Oriented Computing (SOC) domain and the agile software engineering one. This method provides an iterative and incremental process to deliverer business processes, implemented as an assembly of components. This leads to a faster response to the change of needs by reconfiguring the assembly of components. The method is based on a framework that implements its phases as an assembly of components to allow a dynamic reconfiguration of it in case of a development process evolution. Finally, a case study is presented to illustrate the use of the presented method.
