- 12. Cloud Retro Infra overview 1. Worker: spawns games, runs encoding pipeline, streams. Each worker runs multiple game sessions. 2. Coordinator: establishes connections between user and the most suitable worker. 3. Game state storage: stores all game states for durability.
- 13. User flow 1. A client connects to coordinator. 2. Client receives list of available workers. 3. Client checks latency to all running workers. 4. Coordinator picks the most appropriate worker to user. 5. User and the determined worker are connected. The game starts, and the stream are established.
- 14. WebRTC 1. CloudRetro relies on WebRTC for sub-second peer to peer streaming. 2. WebRTC is an open-source project that provides real-time communication via simple API. 3. Built-in VP8/H264 Video compression, Opus Audio compression. 4. NAT traversal. 5. CloudRetro uses Pion WebRTC Library
