Elastic Load Balancing (ELB)
Distributes incoming traffic across EC2/container/Lambda targets across AZs — ALB for Layer 7, NLB for Layer 4. Most-used open-source equivalents: NGINX (L7 reverse proxy/load balancer, dominant choice), HAProxy (L4/L7, high performance, common NLB analogue), and Envoy (cloud-native, common in service-mesh/Kubernetes ingress setups).
