Learn how to modernize monolithic applications using event-driven architecture (EDA) in this comprehensive conference talk from AWS re:Invent 2025. Discover powerful approaches for decomposing complex systems into small, decoupled services that can scale independently. Explore common design trade-offs for distributed systems and navigate them effectively using proven design patterns illustrated through real-world examples. Master the application of integration patterns in complex use cases to successfully transform legacy applications at scale. Gain practical insights into breaking down monolithic architectures and implementing event-driven solutions that enhance system scalability, maintainability, and performance.
