As this book demonstrates, service-oriented architecture (SOA) is finally becoming a concrete discipline rather than a hopeful collection of cloud charts. Based on the author's experience rolling out an SOA at a major mobile phone company, SOA in Practice explains how SOA can simplify the creation of large-scale applications. Whether your project involves a large set of web service-based components or is a means to connect legacy applications to more modern workflows, this book clarifies how and whether SOA fits your needs. In fact, this is the only book that gives you a real understanding of what SOA is about, offering a fundamental overview of what it means to realize SOA in practice without getting lost in theory. After defining SOA's many facets, examining typical use patterns and exploring how loose coupling helps build stronger applications, Josuttis presents a framework to help you determine when to take advantage of SOA. With SOA in Practice, you will:

Focus squarely on real deployment and technology, not just standards maps.
Examine business problems to determine which ones fit an SOA approach before plastering an SOA solution on top of them.
Get concrete 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.

Earlier books on SOA suffered from too much vision and not enough reality. This one describes the real-world problems of implementing and running an SOA in practice. Not only will you learn how to categorize different SOA layers and different SOA stages of extension, you will learn how performance, security and other real-life aspects influence the business case of SOA and the way a SOA is realized. If you're serious about SOA, rely on the experience of someone who's been in the trenches and achieved success. You will find it with SOA in Practice.
