- 1Service Decomposition: Define service boundaries: Auth, User Profile, Course Catalog, Video Streaming, Payment, Notification
- 2Event-Driven: Kafka topics for async communication: CourseEnrolled → triggers Welcome email, Progress update
- 3Video Pipeline: Upload to S3 → Lambda triggers FFmpeg transcoding → multiple resolutions → CloudFront CDN delivery
- 4Infrastructure: Docker Compose for local dev; Kubernetes manifests for production with HPA for video service
Key features to implement
- ✓Adaptive video streaming (HLS with quality switching)
- ✓Course progress tracking with certificates
- ✓Live Q&A sessions with WebRTC
- ✓Recommendation engine based on enrolled courses
- ✓Complete payment flow with Stripe
💡 Unique twist to stand out
Implement a "Cohort Learning" feature: group students who enrolled in the same week into cohorts with shared discussion boards and a peer accountability system showing cohort progress rankings.
