About This Architecture

Real-time multilingual video conferencing architecture on GCP combines WebRTC media servers with AI-driven translation pipelines. Users connect via Cloud Load Balancing to Mediasoup media servers in VLAN 10, while PCM audio streams flow to VLAN 20 where Whisper ASR, NLLB-200 translation, and Coqui TTS generate multilingual audio tracks. Cloud Pub/Sub and RabbitMQ coordinate translation jobs across GKE-orchestrated microservices, with Cloud Spanner maintaining global session state and BigQuery capturing analytics. This architecture demonstrates how to build low-latency, globally distributed video platforms with live language translation using GCP managed services and open-source WebRTC components. Fork this diagram on Diagrams.so to customize VLAN segmentation, swap translation engines, or add your own AI models for speech processing.
