Configuring Load Balancers

Overview

Configure load balancers across AWS (ALB, NLB), GCP (HTTP(S) LB, TCP/UDP LB), Nginx, and HAProxy. Generate production-ready configurations with health checks, SSL/TLS termination, path-based and host-based routing, sticky sessions, rate limiting, and traffic distribution rules for high-availability deployments.

Prerequisites

• Backend servers identified with IPs, DNS names, and ports
• Load balancer type determined: L4 (NLB, HAProxy TCP) or L7 (ALB, Nginx, HAProxy HTTP)
• SSL/TLS certificates available (ACM, Let's Encrypt, or self-signed) if using HTTPS
• Health check endpoints defined on backend services (e.g., /health returning 200)
• Cloud provider CLI installed for managed load balancers (aws, gcloud)
