Virtual Domain-driven design [Fireside chat] orchestration and choreography with Laila Bougria & Udi Dahan
16 snips
Aug 1, 2023 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.

Episode notes
Orchestration vs. Choreography
- Orchestration uses a central component, like a conductor, to manage the workflow.
- Choreography relies on individual services reacting to events, without a central conductor.
Monolith to Microservices
- Acknowledge that transitioning a monolith to microservices involves suboptimal stages.
- Use "fat events" with lots of data as a temporary, practical step in this transition.
Asynchronous vs. Synchronous Communication
- Analyze your business processes to identify naturally asynchronous steps.
- Determine if a step's failure requires rolling back previous steps to assess coupling.
