Enterprise Services Architecture
Publisher: O'Reilly Media
Released: September 2003
Pages: 224

Enterprise Services Architecture outlines a disciplined and structured approach to understanding how today's enterprise applications will make use of web services. This book, aimed at senior management and IT professionals, presents a forward-looking architecture that can meet future development challenges with ease and agility.

"Enterprise Services Architecture, as described in this book, is an application of service-oriented architecture and sound principles of object-oriented design applied to the current heterogeneous world of IT architecture. Enterprise services are the high-level components that aggregate web services into reusable elements. The new world of Enterprise Services Architecture will change the way all vendors build applications and the way companies use them. Monolithic applications will be broken apart into layers and offered as components. The reduced cost of integration and flexibility will make design, modeling, and architecture vital commodities as companies craft the optimal structure out of these components. The benefit should be the ability to optimize the business without a bottleneck in the IT infrastructure, which is too often the case. The ultimate goal of this book is to help our customers and the marketplace at large come to grips with the architectural revolution that is underway." --Hasso Plattner, Chairman, SAP AG Supervisory Board

Enterprise Services Architecture Review

Comments about oreilly Enterprise Services Architecture:

In the second book in the series between O'Reilly and SAP, author Dan Woods takes the reader through an interesting tour of Enterprise Services Architecture and the evolution of WebServices(WS). He makes a business case for applying WS in the enterprise and argues that despite slow standardization and lack of broader vendor support, WS strategy will surely benefit early adapters.

For starters get this - The concept of Web Services was actually conceived by SAP! Woods shares the historical perspective and speaks about implementing the very first SOA based applications while working at SAP. The thin UI layer of MySAP.com uses a services layer to communicate with loosely coupled components and data services.

This book is aimed at senior management and IT professionals involved in building software solutions for the ever-changing enterprise landscape. This is a book about the philosophical, ideological and evolutionary significance of SOA. In the section titled Making a business case for the use of SOA, Woods looks at Ent.Web Services through the eyes of a consultant, an analyst, a venture capitalist and finally a system integrator, and quotes from the very best industry experts in each of these domains. Beyond the trenches of IT shops, in what Woods describes as Part Engineering discipline and part Computer Science applied to practical business problems, he hypothesizes that pervasive use of Web services will ultimately result in an incremental improvement towards a more efficient society. Efficiency will primarily apply to reduce annoyances of everyday life such as filing for taxes, setting up health insurance or getting a driver s license. Freed up human capital will cumulatively help build efficient, elegant and practical living conditions for all.
