More and more, event storming has become a critically important tool in the architect's palate. It is a way to simultaneously collaborate with business people to understand the problems that the business has to solve and to develop an architecture for the solution. Along the way, you discover the entities, bounded contexts, and events that are essential for an effective choreographed microservice (or reactive) architecture. This session is an in-depth look at event storming and the underlying concepts (from Domain-Driven design). It includes an extensive hands-on demo of the process. You'll come away from this talk with a solid understanding of how event storming works and how to apply it.
