Building Modern Distributed Systems with AWS

" summary

Catalog runs as a Lambda serving images from S3 cached in ElastiCache behind CloudFront and API Gateway, while orders use DynamoDB with DynamoDB strong consistency for deduplicated writes; fulfillment and notifications move via queues and topics using SQS / SNS / EventBridge and streaming for high-throughput telemetry; returns use Step Functions for coordinated retries. Capital One reports decade-long migration since 2014 with full cloud by 2016, 14,000 engineers, two GenAI use cases in 2025, and measurable cost, scaling and deployment-speed improvements using CloudFront + API Gateway + Lambda.
