Building a streaming platform that supports real-time synchronization, high-quality video delivery, and seamless user experiences requires a robust, scalable architecture. Here's how we built Telly.
Architecture Overview
Our infrastructure is built on a microservices architecture, allowing us to scale individual components based on demand while maintaining high availability.
Core Components
Content Delivery Network (CDN) We leverage a global CDN with edge locations in over 50 countries, ensuring low latency for users worldwide. Our intelligent routing system directs users to the nearest edge server automatically.
- *Streaming Engine**
- Our custom streaming engine supports:
- Adaptive bitrate streaming
- Multiple quality options (4K, 1080p, 720p, 480p)
- H.264 and H.265 codec support
- Sub-second latency for live content
Synchronization Service The heart of Duo Hub, our synchronization service uses WebRTC and custom algorithms to maintain perfect timing across all participants, accounting for network conditions and device capabilities.
- *Real-time Communication**
- Built on WebSocket connections, our real-time communication layer handles:
- Voice chat
- Text messaging
- Synchronization signals
- Event notifications
Performance Metrics
- Average latency: < 2 seconds
- 99.9% uptime SLA
- Support for 10,000+ concurrent users per event
- Sub-100ms synchronization accuracy
Security
All content is encrypted in transit using TLS 1.3, and we implement DRM protection for premium content. User data is encrypted at rest and follows industry best practices for data protection.
Future Improvements
- We're continuously improving our infrastructure:
- Edge computing for lower latency
- AI-powered quality optimization
- Enhanced compression algorithms
- Expanded global footprint
Our technical team is committed to delivering the best possible streaming experience.
