Service orientation is a new paradigm, not only for software engineering but also for the broader topic of enterprise architecture. This chapter studies the relevance and impact of the service concept and service orientation to the discipline of enterprise architecture. It provides ideas on how to set up a service-oriented enterprise architecture. It is argued that a service-oriented approach to enterprise architecture provides better handles for architectural alignment and business and IT alignment, in particular.

This chapter introduces a Virtual Enterprise architecture for environmental information management, integration and dissemination. On a daily basis, our knowledge related to ecological phenomena, the degradation of the natural environment and the sustainability of human activity impacts, is growing. As a consequence raises the need for effective environmental knowledge exchange and reuse. In this work, a solution among collaborating peers forming a Virtual Enterprise is investigated. Following an analysis of the main stakeholders, a service-oriented architecture is proposed. Technical implementation options, using web-services or software agents, are considered and issues related to environmental information management, ownership and standardization are discussed.

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 research identifies the gap that there is a convergence of interoperability of Cloud Computing (CC), Service Oriented Architecture (SOA) and Enterprise Architecture (EA). Furthermore, it outlines the existing non dynamic links between EA and SOA that are currently practiced in the industry and confirmed by scholarly articles; and provides a state of art of the link that could exist in practice between cloud computing and SOA as researched from the published scholarly material. This researched paper also refers to the planned research to test this theory first by developing a logical architectural model of such a feasibility followed by a Proof of Concept

Web Services (WS) technologies create the potential for an organization to collaborate with partners and customers by enabling its software applications to transact over the Internet. This collaboration is achieved by carefully incorporating Web Services in the organization’s software applications, resulting in comprehensive Service-Oriented Architecture (SOA) for the enterprise. This incorporation of WS-enabled applications and components in the organization’s overall enterprise architecture requires understanding of the service at three interrelated yet distinct layers: policies, activities, and standards. This chapter describes how the existing business processes of an organization are transitioned in to collaborative business processes that would result in a Collaborative Web- Based System (CWBS). The ideas presented in this chapter have been validated through an action-research carried out by the authors in a large energy supplier organization in Melbourne, Australia.

Enterprise architecture management provides the mechanism for governing enterprise transformations required by changes in the environment. In this article, the authors focus on changes that result from the analysis of information system risks and of their impacts on the services delivered by the enterprise. The authors present how the concepts of an information system risks management domain can be integrated into the ArchiMate enterprise architecture modelling language. This article approaches the conceptual integration in two design cycles: first, this article will consider information security risks, and then the authors generalize to information system risks. Additionally, the authors illustrate the application of the proposed approach and demonstrate the benefits of the integrated model through the handling of a case study, first in the domain of information security, and then in the domain of information privacy. The generalized risk-oriented EA model leads to a risk integration framework for the service-oriented enterprise.

In 2000, the United States Federal Bureau of Investigation (FBI) initiated its Trilogy program in order to upgrade FBI infrastructure technologies, address national security concerns, and provide agents and analysts greater investigative abilities through creation of an FBI-wide network and improved user applications. Lacking an appropriate enterprise architecture foundation, IT expertise, and management skills, the FBI cancelled further development of Trilogy Phase 3, Virtual Case File (VCF), with prime contractor SAIC after numerous delays and increasing costs. The FBI began development of Sentinel in 2006 through Lockheed Martin. Unlike in the case of Trilogy, the FBI decided to implement a service-oriented architecture (SOA) provided in part by commercial-off-the-shelf (COTS) components, clarify contracts and requirements, increase its use of metrics and oversight through the life of the project, and employ IT personnel differently in order to meet Sentinel objectives. Although Lockheed Martin was eventually released from their role in the project due to inadequate performance, the project is still moving forward on account of the use of best practices. The case highlights key events in both VCF and Sentinel development and demonstrates the FBI’s IT transformation over the past four years.
