At Your Service: Service-Oriented Computing from an EU Perspective (Hardcover)

Service-Oriented Applications and Architectures (SOAs) have captured the interest of industry as a way to support business-to-business interaction, and the SOA market grew by $4.9 billion in 2005. SOAs and in particular service-oriented computing (SOC) represent a promising approach in the development of adaptive distributed systems. With SOC, applications can open themselves to services offered by third parties and accessed through standard, well-defined interfaces. The binding between the applications and the services can be, in this context, extremely loose--enabling the ad hoc creation of new services when the need arises. This book offers an overview of some current research in the field, presenting the results of eighteen research projects funded by the European Community's Information Society Technologies Program (IST). The projects, collaborations between industry and academia, have produced practical, achievable results that point the way to real-world applications and future research. The chapters address such issues as requirement analysis, design, governance, interoperability, and the dependability of systems made up of components owned by third parties. The results are presented in the context of two roadmaps for research, one developed by European industry involved in software development and the other by researchers working in the service area. The contributors report first on the "Infrastructure Layer," then (in the bulk of the book) on the "Service Integration Layer," the "Semantic Layer," and finally on the issues that cut across the different layers. The book concludes by looking at ongoing research on both roadmaps.

服務導向應用和架構（SOA）已引起業界的關注，作為支持企業間互動的一種方式，並且SOA市場在2005年增長了49億美元。SOA，特別是面向服務的計算（SOC），代表了開發適應性分散系統的一種有前途的方法。通過SOC，應用程序可以開放自己以接入第三方提供的服務，並通過標準、明確定義的接口進行訪問。在這種情況下，應用程序與服務之間的綁定可以非常鬆散，從而在需要時可以即興創建新的服務。本書概述了該領域的一些當前研究，介紹了由歐洲共同體信息社會技術計劃（IST）資助的十八個研究項目的結果。這些項目是工業界和學術界之間的合作，已經產生了實用、可實現的結果，指引了實際應用和未來研究的方向。各章節討論了需求分析、設計、治理、互操作性以及由第三方擁有的組件組成的系統的可靠性等問題。這些結果是在兩個研究路線圖的背景下呈現的，一個是由參與軟件開發的歐洲工業界制定的，另一個是由服務領域的研究人員制定的。貢獻者首先報告了“基礎架構層”的情況，然後（在大部分書中）報告了“服務集成層”、“語義層”，最後報告了跨越不同層次的問題。本書最後介紹了兩個路線圖上的持續研究。
