Answer
Use global load balancers, DNS routing, replicated DBs, stateless JWT sessions, and latency-based region switching with automated failover.
Quick Answer
Multi-region failover: deploy Node.js instances in multiple regions, use global DNS routing (Route 53 latency-based or health-check failover), keep databases replicated cross-region (Aurora Global Database, CockroachDB), use a CDN for static content, and ensure sessions/state are stored in a globally accessible store (Redis Enterprise, DynamoDB global tables).
