This document provides an overview of the technical architecture for an e-commerce website hosted on AWS. It includes DNS resolution with Route 53, content delivery with CloudFront, databases like DynamoDB and RDS, services for workflow, caching, storage, analytics processing, email delivery, and auto-scaling of application components. The website consists of three main services - a front-end catalog, checkout functionality, and marketing/recommendations. Analytics are performed via EMR and stored in S3.
