Product Description

This IDC study assesses the market opportunity for software revenue driven by service oriented architectures (SOAs) in 2004 and presents a forecast for 2005–2009. Historical and forecast revenue data is shown for the total worldwide market, along with segmentation by primary software market. This study does not contain vendor-specific revenue, market shares, or vendor profiles.

“SOA has had a viral impact on the IT industry at large — to a much greater degree than institutional adoption has incurred thus far. But ‘innovation in moderation’ has been the mode of many enterprises, and SOA-based initiatives are no exception. Those that indeed have made headway proceeding down this path have for the most been pleased with the results thus far and fully acknowledge that it is hard work. However, more robust implementations that stand the test of time need to occur to truly gauge how disruptive this trend will truly bear out to be,” said Sandra Rogers, program director for SOA, Web Services, and Integration research at IDC.

SOA Best Practices Report: Beyond Point-to-Point Web Services

Product Description
Service-Oriented Architecture (SOA) emerged as a type of software architecture to build systems through the composition of services. In the enterprise context, SOA permits the organizations, which have a fragmented application infrastructure under management of different domains, can integrate these applications in the service level. The service-oriented paradigm has become a distinct design approach which introduces specific principles that govern the design of architectural elements. In this sense, this book presents a SOA-based architecture process that comprises the main software architecture and SOA foundations in order to guide the architects in the construction of a software architecture description for SOA in an enterprise context. The book begins with an overview of the software architecture and SOA fields, discussing their definitions, roots, foundations and elements. Next, the proposed process is presented with its foundations, roles, activities, sub-activities, inputs and outputs. At the end, an experimental study that was performed using the process is discussed.

A Software Architecture Process for SOA Definition: Designing Service-Oriented Architectures in an Enterprise Context

Product Description

• “This book clearly shows how today’s industry pressures and business challenges mandate renewal of the contract between organizations and their IT assets and people–and it illustrates how a service-oriented approach to IT can help organizations go through the necessary transformation. The role of governance in bringing IT and business closer together is particularly well explained, and the book is worth reading for that alone.”

  –Neil Ward-Dutton, Research Director, Macehiter Ward-Dutton

   

  “It’s easy to pay lip service to the concept of business/IT alignment, but in The New Language of Business, Sandy Carter walks the walk. Few treatments of SOA ground this admittedly difficult topic in the world of business as thoroughly as Sandy has here. I’d recommend this book to any business reader who wants to leverage IT to make their business more agile and innovative, and to any technical reader who wishes to understand how to place SOA in the business context where it belongs.”

  “The New Language of Business: SOA & Web 2.0 is based on the collective feedback from industry leaders at organizations of all sizes, in more than 50 countries, who shared their views, experiences, and challenges of aligning technology with business goals.”

  –From the foreword by Steve Mills, Senior Vice President and Group Executive,  IBM Software Group

   

   

  There is now a direct, provable link between an organization’s flexibility and business performance. To optimize flexibility, companies must achieve unprecedented levels of integration and automation of key processes and infrastructure, both internally and externally. At the same time, they must learn to manage their processes far more dynamically and responsively.

   

  They must become flex-pon-sive*.

   

  Until recently, technology stood in the way of achieving these goals. Thanks to the emergence of service oriented architecture (SOA), Web 2.0, and open standards, technology now enables companies to achieve those goals. In The New Language of Business, one of IBM’s top SOA strategist demonstrates how business leaders can use innovations in technology to drive dramatic process improvements and support accelerating change.

   

  Sandy Carter shows how to deconstruct your business into a “componentized” business model, then support that model with linked, repeatable IT services that can adapt quickly, easily, and economically. These techniques will help both IT professionals and business leaders reach new levels of operational excellence to deliver the market-focused innovations that matter most.

Service-Oriented Architecture Compass: Business Value, Planning, and Enterprise Roadmap

Product Description

The service-oriented approach has become more and more popular, now allowing highly integrated and yet heterogeneous applications. Web services are the natural evolution of conventional middleware technologies to support Web-based and enterprise-level integration.

The highly dynamic characteristics of service-oriented applications means their validation is a continuous process that often runs in parallel with execution. It is not possible to clearly distinguish between the predeployment validation of a system and its use, nor is it possible to guarantee that the checks passed at a certain time will be passed at a later time and in the actual execution environment as well.

Baresi and Di Nitto have put together the first reference on all aspects of testing and validating service-oriented architectures, taking into account these inherent intricacies. The contributions by leading academic and industrial research groups are structured into four parts on: static analysis to acquire insight into how the system is supposed to work; testing techniques to sample its actual behavior; monitoring to probe its operational performance; and nonfunctional requirements like reliability and trust.

This monograph is an initial source of knowledge for researchers in both academia and industry in the field of service-oriented architecture validation and verification approaches. They will find a comprehensive survey of state-of-the-art approaches as well as techniques and tools to improve the quality of service-oriented applications.

Test and Analysis of Web Services

In those days, computers were massive systems based on vacuum tubes and core memory. With the advent of the integrated circuit, computer architectures took a giant leap forward. The mainframe systems of the late 1980’s evolved into Client/Server applications of the early 1990’s. In parallel, the Internet grew from a few engineer and research systems to a World Wide network. It wasn’t until an Al Gore authored bill allowing commerce to be carried out over the Internet did things really start to change. Every business, every organization, had to carve out a space on “The Net.”

The ubiquitous nature of The Internet made it the perfect way for business to have a global reach while maintaining a local presence. Soon, application vendors were making Internet based applications. Today, solution providers are exploiting service oriented architectures and BPEL to provide more agile environments in which to do business.

Today, combining Internet access with massive, inexpensive compute power, data processing has been transformed from an ancillary function of accounting departments to mechanisms by which organizations can transform and enhance their internal processing while integrating their interactions with customers and suppliers.

The key to modern day data processing is not simply the automation of some manual process. Today, business realizes that data processing, information systems, change the very processes that are used to run the business. They not only do same things more efficiently, the do thins differently.

In the past an order was printed and sent to a supplier. The order was received and, if the item was in stock, it was shipped. Items not in stock were placed on back order. Today with Supply chain integration, the entire supply chain is integrated into one network. Warehouse management software notifies suppliers when stock levels drop and order are placed. The suppliers themselves use data mining and CRM (Customer Relationship Management) software to predict ordering patterns and anticipate customer needs.

Even how businesses interact with their customers has changed. In the past, businesses used mass marketing to appeal to the greatness number of possible customers. Today, we have mass customization where businesses on a group basis provide customized goods and services.

Web Services and Formal Methods: 4th International Workshop, WS-FM 2007, Brisbane, Australia, September 28-29, 2007, Proceedings

Product Description

Web services based on the eXtensible Markup Language (XML), the Simple Object Access Protocol (SOAP), and related standards, and deployed in Service-Oriented Architectures (SOA), are the key to Web-based interoperability for applications within and across organizations. It is crucial that the security of services and their interactions with users is ensured if Web services technology is to live up to its promise. However, the very features that make it attractive – such as greater and ubiquitous access to data and other resources, dynamic application configuration and reconfiguration through workflows, and relative autonomy – conflict with conventional security models and mechanisms.

Elisa Bertino and her coauthors provide a comprehensive guide to security for Web services and SOA. They cover in detail all recent standards that address Web service security, including XML Encryption, XML Signature, WS-Security, and WS-SecureConversation, as well as recent research on access control for simple and conversation-based Web services, advanced digital identity management techniques, and access control for Web-based workflows. They explain how these implement means for identification, authentication, and authorization with respect to security aspects such as integrity, confidentiality, and availability.

This book will serve practitioners as a comprehensive critical reference on Web service standards, with illustrative examples and analyses of critical issues; researchers will use it as a state-of-the-art overview of ongoing research and innovative new directions; and graduate students will use it as a textbook on advanced topics in computer and system security.
