Explore how to effectively manage complexity in event-driven architectures through a domain-driven design lens in this 52-minute conference talk from NDC Copenhagen. Learn how event-driven architecture (EDA) extends beyond traditional producer-consumer-broker patterns to create dynamic, evolutionary architectures that enhance organizational agility and innovation. Discover practical strategies for implementing guardrails and governance frameworks that prevent complexity from obscuring EDA's potential benefits. Examine how Domain-Driven Design principles can guide the development of event-driven systems that adapt to rapidly changing business requirements and technological advancements. Gain actionable insights for both refining existing architectures and designing new event-driven solutions, with emphasis on controlling complexity while maximizing the architectural benefits of domain-driven approaches in distributed systems.
