State or Events? Which Shall I Keep?

Explore the benefits and challenges of implementing event-driven architecture through a live coding session focused on tackling complex domains. Dive into a practical example that addresses stakeholder concerns such as quick time-to-market, complex data reporting capabilities, and rapid feature deployment. Examine the developer perspective, including the learning curve for working with events and differences in unit testing approaches. Progress through a step-by-step implementation, clearly identifying problems and benefits at each stage. Cover a wide range of concepts including event sourcing, CQRS, distributed systems, Spring Cloud Stream, eventual consistency, unit testing, and Event Storming with Domain-Driven Design (DDD).
