Messaging and event-driven architecture pattern bring the best out of modeling communication between bounded contexts with distributed systems. This section under DDD intends to ensure you understand the significance of EDA and messaging patterns within the context of DDD. And also to emphasize the benefit of implementing asynchronous messaging and EDA patterns for communication between the contexts. The benefits include increased reliability even on failures of subsystems. We have covered most of the EDA and messaging patterns well and in-depth in Chapter 8, Event-Driven Architecture Patterns, and Chapter 9, Microservices Architecture Patterns, and we encourage you to refer to those chapters and get insights about event-driven and messaging patterns.
