How do you handle service discovery in production?

Expert Microservices Published: Nov 22, 2025

Quick Answer Production service discovery: use Kubernetes Services (ClusterIP) for internal service-to-service DNS-based discovery. Each service gets a stable DNS name (service-name.namespace.svc.cluster.local). Kubernetes kube-proxy handles load balancing. For external services: use cloud provider discovery or Consul. Avoid hardcoded IPs - they change as pods restart and scale.

Answer

Service discovery enables dynamic locating of services in distributed systems.
Methods: Client-side (client queries registry), Server-side (load balancer handles routing).
Tools: Eureka, Consul, Kubernetes DNS.
Supports auto-scaling, failover, and dynamic environments.
