About This Architecture

Six-layer enterprise application architecture with frontend mobile clients, API Gateway for routing and security, Spring Boot backend services, SaaS identity provider, PostgreSQL and S3 data layer, and external integrations. Requests flow from Android/iOS apps through the API Gateway with rate limiting and validation, then to backend services orchestrating business logic and managing authentication via Auth0/Okta. Data persistence uses PostgreSQL and S3, while external systems connect securely via dedicated APIs. This layered design enforces separation of concerns, enables independent scaling, and centralizes security controls at the gateway and identity layers. Fork and customize this diagram on Diagrams.so to match your organization's specific services, authentication provider, and integration endpoints.
