Description

This book demonstrates
service-oriented architecture (SOA) as a concrete discipline rather than a
hopeful collection of cloud charts. Built upon the author's firsthand
experience rolling out a SOA at a major corporation, SOA in Practice
explains how SOA can simplify the creation and maintenance of large-scale
applications. Whether your project involves a large set of Web Services-based
components, or connects legacy applications to modern business processes, this
book clarifies how -- and whether -- SOA fits your needs.SOA has been
a vision for years. This book brings it down to earth by describing the
real-world problems of implementing and running a SOA in practice. After
defining SOA's many facets, examining typical use patterns, and exploring how
loose coupling helps build stronger applications, SOA in Practice
presents a framework to help you determine when to take advantage of SOA. In
this book you will:

Focus squarely on real deployment and technology, not
just standards maps
Examine business problems to determine which ones fit
a SOA approach before plastering a SOA solution on top of them
Find clear paths for building solutions without
getting trapped in the mire of changing web services details
Gain the experience of a systems analyst intimately
involved with SOA
