"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 BoardThis 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.
