Why This Topology Works
RabbitMQ with dead-letter queues ensures no message is lost during SAP sync failures. Retry policies with exponential backoff handle transient ERP outages gracefully.
Scaling Notes
Queue workers scale based on queue depth. Dead letter queue isolates poison messages for manual inspection without blocking the pipeline.
Observability
Queue depth and consumer lag metrics feed alerting. Failed messages in DLQ trigger PagerDuty notifications.
Typical Bottlenecks
- Service latency and timeout behavior on critical routes
- Queue lag, retry storms, and DLQ growth during incidents
- Third-party SLA variability and quota exhaustion
Async Flow and Reliability
User-facing operations remain synchronous while long-running work moves through queues or streams. Workers consume jobs independently with retry and failure isolation, improving resilience under burst load.
Upgrade Path
Harden each domain with clear ownership, enforce SLO budgets, and adopt multi-region or active-passive failover where downtime costs are high.
Operating Envelope
Complexity is marked as Advanced with an intended scope of Org critical. Use this as a planning baseline before adapting the template to your reliability and team constraints.
