Event-driven architectures often fail at scale due to tight coupling, fragile messaging pipelines, and operational complexity.
Tural Suleymani (Microsoft MVP, Engineering Manager at VOE Consulting) shares how his team designed and evolved a high-scale event-driven microservices system using Azure Cosmos DB Change Feed as the backbone for domain events — running in production under real traffic.
He walks through concrete problems: synchronous service dependencies, ordering guarantees, hot partitions, and consistency tradeoffs. You’ll see how they modeled events per bounded context, selected partition keys that survived scale, and implemented reliable consumers.
Includes a live, repeatable demo of an end-to-end event flow — from write, to Change Feed, to downstream services — with observability and failure handling.
