About This Architecture

Real-time trading order pipeline leveraging AWS MSK, API Gateway, and ElastiCache to process client orders from ingestion through execution and audit. Orders flow from Client through API Gateway to Front Office, then Order Management System, which publishes events to Kafka MSK for downstream consumption by Notification Service, Back Office, and Audit Service. Market Data Service feeds Redis ElastiCache and Stock Exchange, while CloudWatch Monitoring tracks system health across all pipeline stages. This architecture demonstrates event-driven design patterns essential for low-latency financial systems, separating streaming order processing from batch audit workflows to ensure compliance and performance.

How do you design a real-time trading order pipeline on AWS that handles order ingestion, execution, and audit compliance?

This diagram shows a production-grade trading platform using AWS MSK Kafka for event streaming, API Gateway for order ingestion, Order Management System for processing, and separate services for notifications, back office, and audit. ElastiCache provides low-latency market data access while CloudWatch monitors the entire pipeline.
