Typical production setup. Your actual cost is generated based on your specific configuration.
Architecture overview
Syncs a multi-vendor product catalog, routes checkout payments with per-seller splits, processes orders through a fulfillment pipeline, and surfaces products through a full-text search index with personalized recommendations.

Each generated workspace includes provider-aware Terraform starter modules, deployment variables, and environment notes for the selected cloud provider. This preview is intentionally short so the public page stays readable while still showing search engines the implementation artifact.

}Production risks for this architecture
Inventory oversell race condition under flash sale traffic: optimistic locking at the database layer is not enough under burst load — use Redis atomic DECR for real-time inventory counters with DB sync on order confirmation
Payment split timing mismatch with order cancellation: if a seller payout runs before a buyer cancellation window closes, refund processing involves a chargeback cycle — hold payouts until the return window expires
Search index lag causing stale availability: OpenSearch propagation delay means sold-out products can still appear in search results for seconds — filter availability in the API response against the RDS source of truth before rendering
