Answer
Use multi-zone deployment, redundant brokers, replicated DBs, load balancing, leader election, and self-healing mechanisms across all services.
Quick Answer
Fully distributed Node.js: no single server, stateless services (all state in Redis/DB), message queues (Kafka) for async communication, service discovery (Consul), distributed config (etcd), circuit breakers between services, health checks and auto-restart at every level, multi-region deployment with geo-routing, and chaos engineering to verify fault tolerance.
