Building Real-Time Systems That Scale

Architecture decisions behind reliable, high-concurrency WebSocket systems.

Real-time scale is less about one transport choice and more about controlling state ownership, failure domains, and backpressure.

I start with explicit event contracts, server-authoritative state, and observable connection lifecycles. Horizontal scale then becomes a routing problem instead of a rewrite.

Reliability comes from designing reconnects, idempotency, and stale-session cleanup as first-class flows—not exceptions.
