Securing access to information is important to any business. Security becomes even more critical for implementations structured according to Service-Oriented Architecture (SOA) principles, due to loose coupling of services and applications, and their possible operations across trust boundaries. To enable a business so that its processes and applications are flexible, you must start by expecting changes – both to process and application logic, as well as to the policies associated with them. Merely securing the perimeter is not sufficient for a flexible on demand business. In this IBM Redbooks publication, security is factored into the SOA life cycle reflecting the fact that security is a business requirement, and not just a technology attribute. We discuss an SOA security model that captures the essence of security services and securing services. These approaches to SOA security are discussed in the context of some scenarios, and observed patterns. We also discuss a reference model to address the requirements, patterns of deployment, and usage, and an approach to an integrated security management for SOA. This book is a valuable resource to senior security officers, architects, and security administrators.

In cooperation with experts and practitioners throughout the SOA community, best-selling author Thomas Erl brings together the de facto catalog of design patterns for SOA and service-orientation. More than three years in development and subjected to numerous industry reviews, the 85 patterns in this full-color book provide the most successful and proven design techniques to overcoming the most common and critical problems to achieving modern-day SOA. Through numerous examples, individually documented pattern profiles, and over 400 color illustrations, this book provides in-depth coverage of: • Patterns for the design, implementation, and governance of service inventories–collections of services representing individual service portfolios that can be independently modeled, designed, and evolved. • Patterns specific to service-level architecture which pertain to a wide range of design areas, including contract design, security, legacy encapsulation, reliability, scalability, and a variety of implementation and governance issues. • Service composition patterns that address the many aspects associated with combining services into aggregate distributed solutions, including topics such as runtime messaging and message design, inter-service security controls, and transformation. • Compound patterns (such as Enterprise Service Bus and Orchestration) and recommended pattern application sequences that establish foundational processes. The book begins by establishing SOA types that are referenced throughout the patterns and then form the basis of a final chapter that discusses the architectural impact of service-oriented computing in general. These chapters bookend the pattern catalog to provide a clear link between SOA design patterns, the strategic goals of service-oriented computing, different SOA types, and the service-orientation design paradigm. This book series is further supported by a series of resources sites, including soabooks.com, soaspecs.com, soapatterns.org, soamag.com, and soaposters.com.

Endorsed by all major vendors (Microsoft, Oracle, IBM, and SAP), SOA has quickly become the industry standard for building next-generation software; this practical guide shows readers how to achieve the many benefits of SOA Begins with a look at the architectural principles needed to create successful applications and then goes on to examine the process for designing services and SOA implementations Each stage of the design process has an accompanying chapter that walks readers through the details and provides helpful tips, techniques, and examples The author team of SOA practitioners also provides two unique, comprehensive, end-to-end case studies illustrating the architectural and design techniques presented in the book

The Definitive Guide to Service Engineering The key to succeeding with service-oriented architecture (SOA) is in comprehending the meaning and significance of its most fundamental building block: the service. It is through an understanding of service design that truly “service-oriented” solution logic can be created in support of achieving the strategic goals associated with SOA and service-oriented computing. Bestselling SOA author Thomas Erl guides you through a comprehensive, insightful, and visually rich exploration of the service-orientation design paradigm, revealing exactly how services should and should not be designed for real-world SOA.

LetÕs Design On-Demand Business Model _DESCRIPTION Service-Oriented Architecture (SOA) is an architectural approach that can be shared and reused. The book proposes a service-based architecture approach to design an adaptive business model for small enterprises. It presents an ad-hoc model which is based on five layered SOA architecture that can integrate all activities comprising Supply Chain Management (SCM), Customer Relationship Management (CRM), Technical and Enterprise applications tools, and hence, it best suits the SME requirements. This book covers the challenges that SMEs face to compete with large enterprises. It also compares the proposed model with traditional ERP systems and other similar approaches. It is found that the SOA model is efficient, cost-effective, and competent with similar existing solutions. There is always a need to know the scope and size of the work involved while developing a service or deriving any application from service-based model; this book will help in determining the cost and effort for such projects. KEY FEATURES - Guide to investigate series of processes/activities (value chain activities) required in Small and Medium size Enterprises (SME). - Guide for organizations to identify which SOA infrastructure will be needed to build service-based applications for themselves. - Guide for organizations to test the SOA model in order to meet the changing on-demand business requirements and ensure high level of security and governance. - Guide to handle interoperability between different vendor infrastructures. WHAT WILL YOU LEARN The book will cover the detailed study of service-oriented model from the inception of the idea to its final implementation. You will be able to understand the basics components of service-oriented architecture. You will learn how to develop SOA based model and will realize that most of the interoperability problems visible at the conceptual level could be overcome. The successful simulation of integration among business value chain activities by using the service-oriented methodology can be served as guidelines for researchers, system designers, and system stakeholders to obtain integrated and accuracy output information.
