The Challenge
"Delivering high-quality video content requires complex media processing and adaptive streaming to prevent buffering across varying network conditions."
Architectural Solution
Decoupled architecture with Next.js 15 for the presentation layer and a RESTful Express.js API. Orchestrates video encoding via FFmpeg and uses HLS for delivery.
Engineering Deep Dive
An inside look at the structural decisions, trade-offs, and scaling plans devised during implementation.
Context & Constraints
- Video Streaming Architecture.
- Cloud Media Storage (AWS S3) implementation.
- Full-stack development with mission-critical media delivery.
Architecture Trade-offs
Used client-side FFmpeg (WASM) for localized processing to reduce server load, despite higher client-side resource requirements. Relies on S3 direct streaming for simplicity.
Database Modeling
MongoDB for movie metadata and user profiles, utilizing denormalized documents for genre and tag optimization to speed up read queries.
Scaling Plan
Future integration of AWS CloudFront CDN for edge caching and Kubernetes for automated horizontal scaling of the transcoding nodes.
