Event-Driven Patterns for Cloud-Native Banking - What Works, What Hurts?

Event-driven architectures promise scalability, traceability, and resilience - but in a regulated, cloud-native banking environment, they also come with very real challenges. In this talk, we’ll walk through the key patterns we used to build a real-time payment system in Azure - from inbox patterns and event sourcing to idempotency and observability.

You’ll learn where these patterns delivered clear wins - like "free" payment tracking - and where they introduced friction, especially for engineers new to the architecture. We’ll share honest lessons about complexity, onboarding, operational headaches, and what we’d refine next time.

Whether you’re already deep in the trenches of event-driven systems, or brand new to this rabbithole, this talk will help you apply the right patterns for your workloads, and avoid the ones that bite.
