advancedContainerized System Design: Microservices, API Gateway, Event-Driven & Deployment Architectures
What's the core trade-off event-driven architecture makes compared to direct service-to-service calls?
It decouples the producer from needing any knowledge of who (if anyone) consumes an event, and decouples their relative speed too — but it trades away an immediate response, making it wrong for anything that genuinely needs a synchronous answer the calling code must act on right away.
