e-Business and SoA

I started writing a Paper on Service Oriented Architecture and Realities of it. Being an e-Business domain professional, no matter which architecture or technology I talk about, my li'l brain always visualises the applications from the e-Domains.My Paper is not proceeding any further as I am being haunted by the question that Most of the B2B applications are Event Driven rather than Service Oriented. So there is a power shift in my zooming ahead and as usual I am reflecting my thoughts on my blog jus to make sure I dont miss my piece of cerebrum.

Recognizing that most B2B interactions are more event-driven than service-oriented because they have traditionally been — and will continue to be — one-way interactions between applications with separate Logical Units of Work. Event-driven architecture and service-oriented architecture have many similarities. Both support distributed applications that go beyond conventional architectures, both use a modular design based on reusable business components, and both may be enabled through Web services. Architects and developers must understand the business requirements and process models to determine whether SOA, EDA or some combination of them is right for each aspect of each new business process. This is where I am right now....Thinking n thinking...........
