In this course, you will explore what Service-Oriented Architecture (SOA) is, the impact of SOA, what it means in terms of today's systems and architectures, and how to apply the concepts in identifying business and systems services. You will gain a better understanding of what services and SOAs are, and the best practices and processes used in supporting the design and implementation of SOA-based applications. You will examine the enterprise systems and how to identify, design, and develop complex services using sound analysis and design techniques. You will have a clear picture of how a service orientation can fundamentally change the dynamics of how software is developed and "lives" within an enterprise.

You will leave this course armed with the required skills to support the design and implementation of realistic SOA-based business application projects. You will also cover advanced SOA concepts and practices for enterprise applications. Multiple detailed lab exercises throughout the course are designed to reinforce fundamental skills and concepts learned in the lessons.
