Service Orchestration As Organization

Service orchestration techniques combine the benefits of Service Oriented Architecture (SOA) and Business Process Management (BPM) to compose and coordinate distributed software services. On the other hand, Software-as-a-Service (SaaS) is gaining popularity as a software delivery model through cloud platforms due to the many benefits to software vendors, as well as their customers. Multi-tenancy, which refers to the sharing of a single application instance across multiple customers or user groups (called tenants), is an essential characteristic of the SaaS model. Written in an easy to follow style with discussions supported by real-world examples, Service Orchestration as Organization introduces a novel approach with associated language, framework, and tool support to show how service orchestration techniques can be used to engineer and deploy SaaS applications. Describes the benefits as well as the challenges of building adaptive, multi-tenant software service applications using service-orchestration techniques Provides a thorough synopsis of the current state of the art, including the advantages and drawbacks of the adaptation techniques available Describes in detail how the underlying framework of the new approach has been implemented using available technologies, such as business rules engines and web services

A very practical publication that contains the knowledge of a large number of experts from all over the world. Being independent from specific frameworks, and selected by a large board of experts, the contributions offer the best practical guidance on the daily issues of the IT manager.

Information and communication technology (ICT) is permeating all aspects of service management; in the public sector, ICT is improving the capacity of government agencies to provide a wide array of innovative services that benefit citizens. E-Government is emerging as a multidisciplinary field of research based initially on empirical insights from practice. Efforts to theoretically anchor the field have opened perspectives from multiple research domains, as demonstrated in Practical Studies in E-Government. In this volume, the editors and contributors consider the evolution of the e-government field from both practical and research perspectives. Featuring in-depth case studies of initiatives in eight countries, the book deals with such technology-oriented issues as interoperability, prototyping, data quality, and advanced interfaces, and management-oriented issues as e-procurement, e-identification, election results verification, and information privacy. The book features best practices, tools for measuring and improving performance, and analytical methods for researchers.

This book introduces a new industry technology, Business Service Orchestration (BSO). Section I provides detailed overview of business services and their orchestration and describes an in-depth architecture necessary to provide a web of business services, and orchestration of their interactions, including a methodology for modeling the BSO. Section II focuses on technologies necessary to orchestrate business services, ranging from component models to programming languages to various kinds of protocols. Section III reveals a real use case and explains how to apply orchestration to a real-life business process.

During the last decade, interoperability has emerged as a vivid research area in electronic business and electronic governance, promising a significant increase in productivity and efficiency of information systems, enterprises and administrations. Interoperability in Digital Public Services and Administration: Bridging E-Government and E-Business provides the latest research findings such as theoretical foundations, principles, methodologies, architectures, technical frameworks, international policy, standardization and case studies for the achievement of interoperability within the provision of digital services, from administration and businesses toward the user citizens and enterprises.

This book constitutes the refereed preceedings of the Third International Workshop on Technologies for E-Servies, TES 2002, held in conjunction with VLDB 2002 in Hong Kong, China in August 2002. The 14 revised full papers presented together with 4 invited papers were carefully reviewed and selected. Among the topics addressed are database issues for e-services, b2b integration, model transformation, process-based application development, information fusion, information integration, business relation management, mobil servies, trust-based web security models, etc.

The TCGOV 2005 international conference on e-government was held at the Free University of Bozen-Bolzano during March 2–4, 2005. The conference was initiated by the working group “Towards Electronic Democracy” (TED) of the European Science Foundation and was jointly organized by the Free University ofBozen-Bolzano,theMunicipalityofBozen-Bolzano,theTEDWorkingGroup, and the IFIP Working Group 8.5. The conference addressed a large spectrum of issues that are relevant and have to be investigated for a successful transition from the traditional form of government to a new form known as e-government. The main focus was on the following topics: – improving citizen participation and policy making (e-democracy) – government application integration – semantic Web technologies for e-government – security aspects for e-government services Two sessions were dedicated to e-democracy, an emerging area within- government that seeks to enhance democratic processes and provide increased opportunities for individuals and communities to be involved in governmental decisions.Thecontributionsofthesetwosessionscovermorefundamentalresults and insights as well as experiences from di?erent countries. Another focus was on government application integration and the use of - mantic Web technologies, which are important technical aspects on the agenda of e-government research. Di?erent architectures for the integration and orch- tration of distributed services and processes were presented along with two case studies. Three papers about Semantic Web technologies discussed the use of ontologies in e-government.
