Modeling Orchestration and Choreography in Service Oriented Architecture

So far, the general approach towards SOA has been that it is just a tidying-up of application integration. SOA, according to this approach, is not about building new a business functionality but about organizing existing systems. In this article by Michael Havey, we will see that, in reality, SOA is more than merely getting organized. Its principal mandate is to build something new; indeed, SOA is fundamentally about building new processes. We will consider an approach to SOA architecture that is, yes, methodical, but has the burden of actually designing new and challenging orchestration and ESB processes.
