As enterprises connect ERP, CRM, supply chain, and digital channels, synchronous calls create fragile coupling and cascading timeouts. Event-driven patterns publish domain facts—order placed, inventory adjusted, identity provisioned—so consumers react independently without blocking the producer.
Patterns that survive production load
Start with a shared event taxonomy and schemas, not ad-hoc messages. Prefer durable brokers or streaming platforms with retention, replay, and dead-letter handling. Combine events with APIs where commands need strong confirmation, and keep idempotency keys so retries do not double-post financial or inventory updates.
Observability is part of the architecture: correlate event IDs with business transactions, alert on lag, and document who owns each topic. Choreography reduces central orchestration bottlenecks, but only when contracts and SLAs are explicit. Treat schema evolution as a product change with consumers notified before breaking fields disappear.
