Event-driven architecture experts Udi Dahan and Laila Bougria discuss the challenges of coordinating work in event-driven architectures. They explore the differences between orchestration and choreography, the types of events and their contexts, evolving contracts in a message system, observability tools, and the role of SLAs. They emphasize evaluating the entire workflow and the necessity of each step in complex workflows.

Udi Dahan discusses the CQRS architectural pattern, its relation to the command pattern, event ordering, event sourcing, and its popularity in different programming communities. He also provides resources for learning more about CQRS.

Experienced software architects Vaughn Vernon and Udi Dahan discuss the importance of using the right architectural styles and patterns, including service-oriented architecture, event-driven architecture, and sagas. They emphasize the need for communication among developers, avoiding over-application of event-driven architecture, and using sagas for complex business processes.
