Event-Driven Architecture (EDA) isn't just for asynchronous broadcasting. You can build scalable, synchronous request-reply workflows using event choreography instead of tight HTTP/gRPC service calls. By establishing a rigid, immutable four-tier topic naming standard (domain.subdomain.type.version) and bridging the synchronous client connection at the API Gateway using an Edge Correlation Map, microservices remain entirely stateless, decoupled, and easily extensible.
