The first one  Six Design Patterns for Event-Processing Applications shows the logical design patterns used for different types of event driven systems, and should be helpful to practitioners who are designing and implementing such systems. The second note The Growing Impact of Commercial Complex-Event Processing Products explores the commercial offerings for complex event processing. These capabilities were once the real of esoteric systems such as program trading, but are increasingly being used by mainstream commercial enterprises to create highly responsive, situationally aware systems and processes. Finally, the third one Smart Devices and Sense-and-Respond Systems Are Event-Driven lays out the foundations of event driven systems, and how event driven models can interact and coexist with systems that process according to other models.

Interest in event driven capabilities is growing at an astonishing rate, and nearly all the designs we see for modern systems include some event driven capabilities. I would encourage anyone who is designing, building or integrating systems to take a look at this research, as it represents a major trend in the future of application design and architecture.
