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. Many companies proclaim that they don't know where to begin with SOA, while others have begun their SOA effort but haven't reaped the benefits they were convinced it would bring. "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. "SOA Made Simple"ù demystifies SOA, simply. It is not difficult to grasp, but for various reasons SOA is often made unnecessarily complex. Service-orientation is already a very natural way of thinking for business stakeholders that want to realize and sell services to potential clients, and this book helps you to realize that concept both in theory and practice. You'll begin with a clear and simple explanation of what SOA is and why we need 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. After reading "SOA Made Simple"ù you will have a clear understanding of what SOA is so you can implement and govern SOA in your own organization.

The way to approach this is to create a roadmap. A roadmap is a plan that matches short-term and long-term goals with work packages. It consists of work packages in a specific order.

Work packages

There are several ways of attacking this. You can decide to build service by service, process by process, feature by feature, or a mixture of these three.

Service by service

This means you organize your project scope around entire services. You identify, design, and implement an entire service before you move on to the next service. In our recruitment outsourcing example, two services were identified: HR service and a financial service. If you decide to realize service by service, it means that you first finish the HR service, before you realize the financial service. Often the problem with this approach...
