Multi-tier music streaming application architecture with React frontend, Express backend, and AWS-integrated storage services. Client layer supports Guest, User, Artist, and Admin roles connecting to a React + Vite + TypeScript web app with real-time Socket.IO capabilities. Backend API Server in Express handles REST endpoints, authentication, business modules (Auth, Playback, Playlist, Album, Artist Studio, Admin, AI), and integrates with MySQL via Prisma ORM, Supabase Storage for audio, Cloudinary for images, Redis for caching, and external services like VNPay and OAuth. This architecture demonstrates role-based access control, real-time communication, and scalable microservice patterns essential for production music platforms. Fork and customize this diagram on Diagrams.so to adapt storage providers, add AWS Lambda for serverless functions, or extend business modules for your streaming use case.
