Cloud computing has emerged as a powerful new technology. The processing and computation power embedded in the cloud technology is not only flexible but also infinitely scalable and cost effective. Service oriented architecture (SOA) is a perfect stage for cloud computing. SOA has allowed customers and organizations to achieve cloud computing and reap its benefits that would not have been possible through any other architecture. This paper discusses the concept and importance of service oriented cloud computing by highlighting possible architectures, their benefits and critical success factors.

Web services are playing a pivotal role in business, management, governance, and society with the dramatic development of the Internet and the Web. However, many fundamental issues are still ignored to some extent. For example, what is the unified perspective to the state-of-the-art of Web services? What is the foundation of Demand-Driven Web Services (DDWS)? This chapter addresses these fundamental issues by examining the state-of-the-art of Web services and proposing a theoretical and technological foundation for demand-driven Web services with applications. This chapter also presents an extended Service-Oriented Architecture (SOA), eSMACS SOA, and examines main players in this architecture. This chapter then classifies DDWS as government DDWS, organizational DDWS, enterprise DDWS, customer DDWS, and citizen DDWS, and looks at the corresponding Web services. Finally, this chapter examines the theoretical, technical foundations for DDWS with applications. The proposed approaches will facilitate research and development of Web services, mobile services, cloud services, and social services.

Despite its origins, openness in the judiciary has expanded beyond transparency and, therefore, beyond the common law open justice principle. Several initiatives worldwide are echoing this trend and a new term, open judiciary, is arising as a way to address openness in the justice field. This chapter gives an overview of open judiciary initiatives worldwide, focusing on some of the most successful, in order to identify drivers of adoption, critical success factors, and preliminary results. The research is embedded in a broader exploratory study on the state of the art of open judiciary. The chapter is addressed to answer two of the research questions: What are some learning practices that can be identified worldwide in relation to openness in the judiciary? What are some of the most important lessons that can be learnt from these practices?

Systematic Synthesis

Information Technology (IT) projects are more and more aligned with business goals. Service Oriented Architecture (SOA) was introduced to achieve this, align business with IT, and increase IT flexibility, reuse of services in more manageable way. Unfortunately, healthcare organisations that have adopted SOA have yet to benefit from their investment. Industry analysts and academics agree that SOA Governance is a critical success factors for SOA projects. Addressing the substantial research gap, this chapter investigates longstanding challenges and proposes a SOA Governance framework as a way to improve IT/SOA success and guide the alignment of IT and business. The authors present a systematic synthesis of the latest research findings and professional experience on SOA Governance considerations for successful IT projects.

In adoption process of Service Oriented Architecture (SOA), the legacy systems of a company can not be neglected. The reason is the legacy systems have been deployed in the past and have been running critical business processes within an enterprise in its current IT architecture. However not all migration process of legacy systems to SOA has been successfull. Highlighting the right factors to reach legacy systems migration success in a specific company is the key value. The main adopted research method in this study has been interviewed for different companies with different enterprises including bank, furniture, engineering and airline companies in Europe. Through separate interviews, critical success factors of migrating legacy systems into SOA have been collected and identified in each case company. Finally collected results are analyzed and presented as the recognized factors affecting successful migration oflegacy assets into SOA from business and technical perspectives.

Service Oriented Architecture (SOA) Governance is a critical factor for the success of SOA implementations, yet a detailed SOA Governance framework is lacking. The paper reintroduces a conceptual SOA Governance framework in a healthcare setting. The proposed framework is based on a rigorous literature review and consist of nine governance elements that should be considered during the SOA practice. The identification and conceptualisation of the elements are grounded in the normative literature. Moreover, the authors propose a unique formulation combining nine elements of SOA Governance with SOA Critical Success Factors (CSFs) and Healthcare Information Systems (HIS) challenges. This proposal aims to pinpoint attributes and guidelines for each element, required to successfully govern SOA and tackle longstanding HIS challenges. The framework is intended to be used as a decision supporting tool for SOA governance in a healthcare setting.

Many vendors have acclaimed Service Oriented Architecture (SOA) as a better way to design and build enterprise-wide information systems (EWIS). While these claims may be true in the private sector, there is scant evidence in the literature for the same success in the public sector. The adoption of Enterprise-wide SOA (ESOA) as the dominant development paradigm within an organization often requires significant organizational changes, which are difficult to achieve in the public sector, with its strict hierarchies and departmental independence. Although many government departments are beginning to adopt this new paradigm, the literature does not provide a suitable ESOA implementation readiness framework for use in the public sector. This research proposes a framework based on Critical Success Factors (CSFs) and a CSF scorecard to evaluate an organisation’s ESOA implementation readiness. The framework and scorecard were tested in a test case in the Malaysian government, and the results validate the accuracy and usefulness of both the CSF Framework and the CSF Scorecard.

The requirements on gratings and coatings for astronomical use differ from the general industrial requirements primarily in the scale of the components to be fabricated. Telescopes have large primary mirrors which require large coating plants to handle the components. Dispersive elements are driven by the requirement to be efficient in the presence of large working apertures, and usually optimize to large size in order to efficiently use the incoming radiation. Beyond this, there is a “new” technology of direct electronic sensors that places specific limits upon the image scale that can be used at the output of a telescope system, whether direct imagery or spectrally divided imagery is to be examined. This paper will examine the state of the art in these areas and suggest some actions and decisions that will be required in order to apply current technology to the predicted range of large new telescopes.
