Regional load balancing with sticky sessions
Keep user sessions where they belong. Route by region, fail over smartly, and scale horizontally with zero session drift.
Why UltraLoad
Built for Flowless + Flowfull. Session-aware by design.
Regional routing
Send users to the closest healthy region automatically.
Sticky sessions
Affinity that respects app tokens and session cookies.
Smart failover
Health checks and graceful reroute with zero cold-start surprises.
Configuration
Simple YAML-based routing rules
- Works with Flowless/Flowfull tokens for sticky affinity
- Regional policies: pin, prefer, or exclude regions
- Observability: per-region latency and failover events
Example policy
Pin users to home region, failover on health drop
ultraload.route({
regionPreference: ["iad", "gru", "dub"],
sticky: {
cookie: "session_token",
fallback: "bridge", // re-pin using Bridge validation
},
failover: {
thresholdMs: 500,
retries: 2,
},
});>99.99%
