About This Architecture

AWS Centralized Price Feed System ingests real-time commodity and FX rates via scheduled ECS Collector Tasks, caching normalized prices in ElastiCache Redis and persisting to RDS PostgreSQL across multi-AZ deployments. External Trading, Portfolio, and Analytics backends consume prices through a WAF-protected ALB fronting stateless ECS Price API instances in separate AZs, with Trading Safety Layer validation triggering SNS anomaly alerts. This architecture demonstrates high-availability financial data distribution with built-in observability via CloudWatch Logs, X-Ray tracing, and CloudTrail audit logging, isolating ingestion, API, and data tiers across private subnets. Fork this diagram to customize collector schedules, add DynamoDB for sub-millisecond lookups, or integrate with EventBridge for event-driven price updates.

How do I design a scalable, multi-AZ AWS price feed system that ingests commodity and FX rates and distributes them to multiple trading backends with anomaly detection?

This diagram shows a three-tier AWS architecture: Collector Tasks ingest Metals API and FX Rates on a 30-60s schedule, writing to ElastiCache Redis and RDS PostgreSQL; stateless ECS Price API instances behind a WAF-protected ALB serve external backends via Route 53; and Trading Safety Layer validates prices, triggering SNS alerts for anomalies.
