Is there room for improvement in the way your network SOA enables applications to communicate and perform services for one another? Then you'll want to take a serious look at Enterprise Services Architecture (ESA), which is fast becoming the leading SOA technology. With ESA, monolithic enterprise applications are broken apart into layers and offered as components that make extensive use of web services. With these components, companies gain the flexibility to craft the optimal IT infrastructure, eliminating bottlenecks and reducing the cost of implementation. Our new guide, Enterprise Services Designing IT for Business Innovation , demonstrates how your enterprise can transform current solutions into technology that will better serve the needs of your customers. Commissioned by the German software development company SAP, this definitive book is ideal for architects, developers and other IT professionals who want to understand ESA in a detailed way-especially those of you who want to move on the technology now, rather than in the next year or two. Each chapter in the book is organized as a set of theoretical and practical questions with answers and examples that offer a clear story. To partition ESA into digestible portions, the authors boiled everything down into five "Conceiving a Vision for ESA" - This section delves deep into the technical aspects of ESA. "Consuming Services"-Using services to solve IT problems within the This business-focused material shows you how services can be consumed immediately to configure standard software to solve a much larger set of problems. "Composing with Services"-Assembling new applications and services from existing This section demonstrates how services can extend standard software by building on existing functionality as much as possible. "Creating Services"-Creating new web services from How new services are created is described to provide technologists a deeper understanding of the tools and processes involved. "Controlling Services" -discusses new forms of governance based on services as well as lifecycle management, operations, security, and standards.

Enterprise Services Designing IT for Business Innovation presents a forward-looking approach that you can use to meet future development challenges with ease and agility.
