THE SERVICE-ORIENTED ENTERPRISE - TOM GRAVES KA...

A service-oriented architecture is fundamental to many new IT applications  from web
development to social software and cloud computing. The same principles can be applied to every
aspect of the service-oriented enterprise - not just in IT. In this book  you'll explore how an
enterprise architecture and viable services can link together to create a simpler yet far more
powerful view of the enterprise  as a dynamic  unified whole. You can use the ideas  principles
and methods described here in business transformation  workflow mapping  system design and much
else besides  in every type of enterprise - including those in which there may be little or no
IT at all. Step by step  you'll walk through the basics of service-oriented architectures  the
four key categories of services and how they connect  and how all of this comes together in
real-world service design  implementation and operations. From this  you'll discover how to
identify and describe the different types ofservices that you need for your enterprise  and how
to distinguish between the services that you can safely outsource  versus those that you do
need to keep in-house. By the end of this book  you'll learn how to construct function models
and service models of your enterprise as a base for service-mapping  and how to pinpoint and
map the information flows you need for service-management and service-performance  to keep
everything on-track to purpose. What You'll Learn See how an enterprise architecture can work
