Cross-border trade financial services platform on AWS integrating foreign trade enterprises, e-commerce platforms, and regulatory authorities through a three-layer DFD architecture. The Access Layer ingests trade scenarios via 22 standardized APIs and WAF protection, while the Processing Layer executes trade background verification, automated FX settlement (reducing cycle time from 2 days to 0.5 hours), and AI-driven compliance reporting using Bedrock and RPA. Data flows through S3 Data Lakes, Aurora RDS, DynamoDB, and Redshift repositories, with real-time stream processing via Kinesis and credit scoring via SageMaker. This architecture demonstrates how privacy-preserving computation and intelligent automation reduce audit overhead by 50% while handling 10M+ monthly transactions.
