First, you learn about versioning of services, and then the relationship with the different stages of a service is investigated. A common way of keeping track of these changes is using version control. Version control is the management of changes to documents, software, and artifacts. Changes are identified by a number or letter code; a version or revision number. Now when do you give your document, data model, or service a new version number? And what type of versioning scheme are you going to apply? Usually, you make a distinction between minor and major versions of a change. How does that work in a service?

SOA Made Simple
Overview of this book
SOA is an industry term which is often preached like a religion rather than taught like a technology, and over time, grasping the concept has become unnecessarily difficult.

"SOA Made Simple"ù unveils the true meaning of Service Oriented Architecture and how to make it successful so that you can confidently explain SOA to anyone!
"SOA Made Simple"ù explains exactly what SOA is in simple terminology and by using real-life examples. Once a simple definition is clear in your mind, you'll be guided through what SOA solves, when and why you should use it, and how to set up, design and categorize your SOA landscape. With this book in hand you'll learn to keep your SOA strategy successful as you expand on it.

You'll then be presented with plain facts about the key ingredients of a service, and along the way learn about service design, layering and categorizing, some major SOA platform offerings as well as governance and successful implementation.
