Quick Answer
Load balancing distributes traffic across healthy instances to maximize throughput and minimize response time. Without it, one instance gets overwhelmed. In Kubernetes, Services do L4 load balancing across pods. Ingress controllers do L7 load balancing with path/host routing. Algorithms: round-robin, least-connections, weighted. Health checks remove unhealthy instances from rotation automatically.
