Technical architecture for a file sharing platform:
Upload handling: Nginx handles file uploads with large upload size limits (client_max_body_size 10G for 10GB file support). Chunked upload support for large files. Server-side deduplication with MD5/SHA256 hashing to avoid duplicate storage.
Storage: Separate storage from web server. NFS mount or S3-compatible MinIO for storage separation. Organize files by hash prefix for filesystem efficiency (avoid single directory with millions of files).
Download delivery: Nginx X-Accel-Redirect for protected file delivery. Rate limiting per user to prevent bandwidth abuse. Optional: paid premium accounts for high-speed downloads without throttling.
Database: MySQL for file metadata (hash, original filename, upload time, owner, views, downloads). File deduplicated by hash - same file uploaded by multiple users stored once.
