Serverless

on YouTube ↗58m

" summary

Built a production learning platform that runs without servers, using AWS Lambda, Firebase and many cloud services; it scales from zero to tens of thousands of concurrent users (60,000+ customers) with near-zero hosting costs and a per-course delivery cost of about US$0.12. Architecture is fully event-driven and push-based: S3 uploads trigger Lambda, which calls Elastic Transcoder, writes results to Firebase and generates signed CloudFront URLs for protected video delivery. The system works in production and scales effortlessly.
