Choosing the Right Architectural Styles and Patterns

In this conversation, Vaughn Vernon and Udi Dahan discuss various topics related to software architecture, including service-oriented architecture (SOA), event-driven architecture, and sagas. They emphasize the importance of using the right architectural styles and patterns in the right places, rather than over-applying or misapplying them. They also discuss the role of patterns in software development and the need for a common language to facilitate communication among developers. Additionally, they explore the strengths and weaknesses of event-driven architecture and the misconceptions around API-first design. Finally, they delve into the concept of sagas as a way to handle complex business processes and policies.
