Abstract
Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications/solutions. To build the service model, SOC relies on the service oriented architecture (SOA), which is a way of reorganizing software applications and infrastructure into a set of interacting services. However, the basic SOA does not address overarching concerns such as management, service orchestration, service transaction management and coordination, security, and other concerns that apply to all components in a service architecture. In this paper we introduce an extended service oriented architecture that provides separate tiers for composing and coordinating services and for managing services in an open marketplace by employing grid services.

Service-Oriented Architecture - A New Alternative to Traditional Integration Methods in B2B Applications

TL;DR: A B2B case study is introduced to show how SOA allows integration between different systems not by rebuilding them from scratch, rather, by leveraging current assets in a way to make them more dynamic, and easy to be changed according to business needs and market circumstances.

Business process execution language for web services

TL;DR: This book focuses on executable processes and comes back to abstract processes in Chapter 4, which can be used to replace sets of rules usually expressed in natural language, which is often ambiguous.

Grid services for distributed system integration

TL;DR: In this paper, the authors focus on the nature of the services that respond to protocol messages and propose a set of services that can be aggregated in various ways to meet the needs of virtual organizations, which themselves can be defined by the services they operate and share.

Web Services Coordination (WS- Coordination)

TL;DR: This specification describes an extensible framework for providing protocols that coordinate the actions of distributed applications, used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed transactions.

Grid Service Specification

TL;DR: Technical details are provided, providing a full specification of the behaviors and Web Service Definition Language (WSDL) interfaces that define a Grid service.

Design Methodology for Web Services and Business Processes

TL;DR: This paper presents a design methodology for web services and business processes and discusses how business process should be described so that services can be properly identified and provide strategies and principles regarding functional and non-functional aspects of web service design.
