Loose coupling is one of the key factors of the success of the Service Oriented Architecture. It allows easy distribution and replacement of components across wide spread networks. The real value of Loose Coupling unfolds when it is used in an Event Driven Architecture (EDA). EDA is the basis of any modern operating system and the key factor of the internet. This presentation gives you a kick-start in orchestrating loosely coupled services via events. Thinking in events is different from classical procedural programming. This session will make you acquainted with the different thinking structures of EDA and the possibilities that lie in them. It explains why loose coupling in combination with EDA will lead into a much leaner overall service-based infrastructure and a lean SOA.
