Event-driven architecture is a concept that is very easy to bond to the CEP as it defines a simple architecture to promote the production, detection, consumption, and reaction to the events. The concept of this architecture is to focus on application components as one of the four possible elements, related as shown in the following diagram:
The idea of event-driven architecture (EDA) is to classify the components in the following four different categories:
Event Producer: Their role in EDA is solely to be creators of events. Everything that can produce an event is considered a producer, whether it is a hardware-based sensor, application-gathering requests, business processes, or any other form of application that can introduce a new event into our architecture.
Event Consumer: Their role in EDA is to listen to the events produced by other components. They can also range from a wide variety of components, from simple listeners in apps to complex dashboards. They...
