Load Balancer Setup

This walks you through setting up load balancers like HAProxy and AWS ELB/ALB/NLB to spread traffic across multiple servers. You get reference guides for HAProxy config files, CloudFormation templates for AWS ALB, health check scripts, and monitoring setups. It covers the practical stuff: session persistence, SSL termination, health checks, and cross-region balancing. The best practices section is genuinely helpful, steering you away from common mistakes like skipping health checks or creating single points of failure. If you're moving beyond a single server or need failover that actually works, this gives you working configs and deployment patterns rather than just theory.

Overview

Deploy and configure load balancers to distribute traffic across multiple backend servers, ensuring high availability, fault tolerance, and optimal resource utilization across your infrastructure.

When to Use

Multi-server traffic distribution
High availability and failover
Session persistence and sticky sessions
Health checking and auto-recovery
SSL/TLS termination
Cross-region load balancing
API rate limiting at load balancer
DDoS mitigation

Quick Start

Minimal working example:

# /etc/haproxy/haproxy.cfg
global
    log stdout local0
    log stdout local1 notice
    maxconn 4096
    daemon

    # Security
    tune.ssl.default-dh-param 2048
    ssl-default-bind-ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256
    ssl-default-bind-options ssl-min-ver TLSv1.2

defaults
    log global
    mode http
    option httplog
    option denylogin
    option forwardfor
    option http-server-close
