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.

Summary


In this chapter, we addressed the problem that a lot of companies face today, their organization and their IT are organized in silos. This leads to duplication of functionality and information and makes it hard and expensive to change and to adapt to changing markets, rules, and regulations. The IT department is not able to deliver solutions and changes fast enough and the business people are not able to communicate their needs well enough. This results in IT that is lagging behind and frustrated people in the organization on both sides.

To solve this problem, we need to design our organization in a way that fits the long-term business goals of an organization. The IT solutions need to be aligned with our organization and with these same goals. To make this possible, architecture should be applied whenever a change is implemented in the organization that involves information (systems). There are different types of architecture that can be applied such as enterprise architecture, solution architecture, and project architecture.

Service Oriented Architecture is a specific reference architecture that helps solve the data and functionality duplication, thus making the companies that apply this more flexible, and operate more efficiently.

In the next chapter, we explain in detail exactly what services and Service Oriented Architecture mean, and how this type of architecture is a solution to the misalignment of business and IT, and for functional and data duplications in the situations that we've mentioned in this chapter.
