The visionary promise of Service-Oriented Computing (SOC) is a world-scale network of loosely coupled services that can be assembled with little effort in agile applications that may span organizations and computing platforms. In practice, services are assembled in a Service-Oriented Architecture (SOA) that provides mechanisms and rules to specify, publish, discover and compose available services. The aim of this chapter is to present the different technologies implementing the new paradigm of SOA: Web Services, UPnP, DPWS, and service-oriented component OSGi and iPOJO. These technologies have been developed and adapted to multiple domains: application integration, pervasive computing and dynamic application integration.

Network Management Architecture

Traditional NM (Network Management) techniques can not be applied on WSN (Wireless Sensor Network) due to its features of low computing ability, tiny memory space, and limited energy. A new NMA (Network Management Architecture) for WSN is needed. In this paper, we design a loosely coupled NMA of WSN based on SOA (Service-Oriented Architecture), and have well defined NM interfaces. Finally, we develop a SOA platform for WSN operations according to the NMA. Based on SOA platform, users can compose and use various NM Web Services by internet depending on their requirements. Heavy tasks which need a great deal of computing resources and storage are executed on the SOA platform. Thus, energy consumption and node computation can be decreased. Moreover, external applications use Web Services to integrate SOA platform for WSN. It lowers the difficulty in integrating different sensor platforms and heterogeneous devices.

The established global business environment is under intense pressure from Asian countries such as Korea, China, and India. This forces businesses to concentrate on their core competencies and adopt leaner management structures. The coordination of activities both within companies and with suppliers and customers has become a crucial competitive advantage. At the same time, the Internet has transformed the way in which businesses run. As the Internet becomes a cheap and effective communication channel, businesses are quick to adopt the Web for integrating their systems together and linking them with their suppliers and customers. Current enterprise computing using J2EE (Java 2 Platform, Enterprise Edition) has yielded systems in which the coupling between various components in them are too tight to be effective for ubiquitous B2B (business-to-business) and B2C (business-to-consumer) e-business over the Internet. This approach requires too much agreement and shared context between business systems from different organizations. There is a need to move away from tightly coupled, monolithic systems and toward systems of loosely coupled, dynamically bound components. The emerging technology, Web services, provides the tools to accomplish this integration, but this approach presents many new challenges and problems that must be overcome. In this article, we will discuss the current approaches in enterprise application integration (EAI) and the limitations. There is also a need for service-oriented applications, that is, Web services. Finally, the challenges in implementing Web services are outlined.

Event Based

The success of the Internet and the ongoing globalization led to a demand for new solutions to meet the requirements for ITsystems. The paradigm of service-oriented and event-driven architecture with fine grained and loosely coupled services tries to cope with those needs. Service Oriented Architecture (SOA) and Event Driven Architecture (EDA) are two acknowledged architectures for the development of business applications and information systems, which have evolved separately over the years. Today both architectures are acknowledged, but their synergy is not. There are numerous benefits of having an architecture that supports coexistence between operations and events, and composition of services based on operation invocation and event triggering. As part of our ongoing research work, we have tried to analyze in this paper, the basic design of Event based systems, issues that have to be addressed when event based approach is used for composing and coordinating web services. Then we have specified the techniques available that handle these issues, and gave a comparative study on these techniques. Finally we have attempted to sort out the unhandled/ partially handled issues that could be addressed as part of our research.

Host Organization

For centuries, organizations have been trying to exchange information between their applications by linking them together. However, such application integration has not been as successful as organizations have hoped. With the introduction of SOA, application integration is more successful than the previous integration techniques. SOA is a design philosophy in which resources are cleanly partitioned into remotely accessible software components performing self-contained functionalities, called services. The reinvention of SOA in recent times is attributed to the rise of Web Services, which has become commonly used in VLITP to expose services within the host organization. However SOA can also be implemented with other service exposing techniques. SOA is based on the concept of separation of concerns, realizing that no single entity can be best at everything. SOA is usually implemented using an Enterprise Service Bus (ESB). The ESB is responsible for routing, prioritizing, scheduling, monitoring, and controlling the flow of traffic between services and therefore forms the middleware for Service Orientation.

Definition Of

Service-oriented architecture (SOA), Web services, and service-oriented computing (SOC) have become the buzz words of the day for many in the business world. It seems that virtually every company has implemented, is in the midst of implementing, or is seriously considering SOA projects, Web services projects, or service-oriented computing. A problem many organizations face when entering the SOA world is that there are nearly as many definitions of SOA as there are organizations adopting it. Further complicating the issue is an unclear picture of the value added from adopting the SOA or Web services paradigm. This article attempts to shed some light on the definition of SOA and the difficulties of assessing the value of SOA or Web services via return on investment (ROI) or nontraditional approaches, examines the scant body of evidence empirical that exists on the topic of SOA, and highlights potential research directions in the area.

Web Services (WS) technologies, generally built around the ubiquitous Extensible Markup Language (XML), have provided many opportunities for integrating enterprise applications. However, XML/Simple Object Access Protocol (SOAP), together with Web Services Definition Language (WSDL) and Universal Description Discovery and Integration (UDDI), form a comprehensive suite of WS technologies that have the potential to transcend beyond mere application integration within an organization, and to provide capabilities of integrating processes across multiple organizations. Currently, the WS paradigm is driven through parameters however; the paradigm shift that can result in true collaborative business requires us to consider the business paradigm in terms of policies-processes-standards. This chapter, based on experimental research carried out by the authors, demonstrates how the technologies of WS open up the doors to collaborative Enterprise Architecture Integration (EAI) and Service Oriented Architecture (SOA) resulting in Business Integration (BI). The chapter also provide a quantitative investigation based on organization’s adaptation to mobile and Web Services technologies.

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.
