Editorial Reviews

Product Description

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 This book was commissioned by SAP and will be used by SAP to promote their products. We're making it available through our retailers because we believe the information in it is of interest to readers outside of SAP's immediate sphere.

1.0 out of 5 stars marketing material, November 16, 2005

By	A. Irwin (Seattle, WA USA) - See all my reviews (REAL NAME)

This book and its sister book on PCA does exactly what the introduction says it won't, it's nothing but marketing material. It is full of consultant doublespeak and absolutely no substance.

3.0 out of 5 stars More about history than about technology...good for managers, March 24, 2004

By	Ajith Kallambella (JavaRanch.com) - See all my reviews (REAL NAME)

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.

By	Andrea Maraviglia - See all my reviews (REAL NAME)

ESA is a book a lot interested. In it we find a clear explanation of the reasons that have carried the company leader in the computer science solutions for the companies, SAP AG, has to develop to this architecture founded on the principles of the service oriented architecture where the fundamental members are the enteprise services. They are an aggregation of web services with a value of business that they render them works them to the processes that must support. Thanks to ESA the IT transforms from neck of bottle to one fundamental instrument for the change.
