About This Architecture

Scalable e-commerce platform architecture combines React frontend with FastAPI microservices backend, distributed across three server instances behind an API Gateway. Traffic flows from users through CDN and Load Balancer to React Frontend, while API requests route through API Gateway to FastAPI Server 1, 2, and 3, each connecting to Redis Cache for session management and MySQL Primary for transactional data with Read Replica for query optimization. This architecture demonstrates production-grade patterns for high-availability e-commerce: horizontal scaling of FastAPI services, separation of read/write database operations, asynchronous processing via Message Queue to Email Service, and integration with Auth Service and Payment Gateway for secure transactions. Fork this diagram on Diagrams.so to customize component configurations, add your own microservices, or export as .drawio for team documentation. Object Storage handles product images and assets, while Monitoring and Logging services provide observability across the distributed system.
