Explore the transformative power of event-driven architecture in modern systems through this 54-minute Devoxx conference talk. Delve into the nature of events, their growing importance, and how to effectively design event-driven systems. Learn how this approach can enhance autonomy, reduce risk, increase certainty, promote loose coupling, and improve scalability, resilience, and traceability. Gain insights into the theoretical foundations of event-driven design, practical tools and techniques for implementation, and potential pitfalls to avoid. Discover the relationship between events and domain-driven design, understand the distinctions between commands and events, and examine the role of events in defining bounded contexts. Witness practical demonstrations using the Actor Model and explore concepts such as inventory logic, receive logic, scaffolding, and persistence in the context of reactive micro-systems.
