Modeling Uncertainty - DDD Today

Explore Domain-Driven Design (DDD) and its application in modern software development through this 52-minute conference talk by DDD expert Vaughn Vernon. Delve into the essence of DDD, context mapping, and the challenges of modeling uncertainty in distributed systems. Learn about reactive systems, microservices, and the importance of core domains. Discover modeling heuristics and practical approaches to handling events, duplicates, and ordered sequences in complex software architectures. Gain insights into the evolution of DDD from 1973 to the present day, and understand how it addresses current challenges in cloud computing, latency management, and system reactivity.
