Why This Topology Works

CDN absorbs read traffic, Kafka decouples order processing from search indexing, and Elasticsearch provides sub-50ms product queries. Each tier scales independently under load spikes.

Scaling Notes

CDN handles 90%+ of read traffic. Kafka consumers auto-scale for order processing. Elasticsearch cluster shards across availability zones for resilience.

Observability

Distributed tracing across API Gateway → services → Kafka consumers. Elasticsearch slow-query logs alert on degraded search performance.

Typical Bottlenecks

  • Deployment drift and regional resource saturation
  • Frontend rendering and bundle delivery under peak traffic
  • Service latency and timeout behavior on critical routes

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-scale commerce. Use this as a planning baseline before adapting the template to your reliability and team constraints.
