However, as application complexity increases, the coupling of services becomes an impediment in adapting applications to meet the ever-changing goals of the business. Event Driven Architecture (EDA) is a method of designing and implementing systems where events are exchanged between highly decoupled components and services. EDA does not replace SOA, instead it compliments the request/response nature of SOA with a highly scalable event model for building and coordinating asynchronous transactions. This presentation explain event driven architecture, describe the different types of events, demonstrate how events can be related and orchestrated, and provide a basic understanding of how this method can drive the architecture of enterprise systems. In addition to understanding the concepts of event driven architecture, we will explore a working sample built using an open-source .NET messaging framework called MassTransit.
