System design

  • How to implement a distributed and auto-scalable WebSocket server architecture on Kubernetes

    • how to find a sender id if it is not found locally

      • Pub/Sub solution (can be expensive)

      • rendezvous hashing taking instance_ids (from K8s API) and sender_id (looks better)

    • how to load balance WebSocket re/connections

      • least_connection algorithm to balance connections to new instances

      • clients may need to be able to reestablish WebSocket connections
