Load Balancer Configurator

Load Balancer Configurator generates complete, production-tested load balancer configurations for the three most common scenarios: Nginx as a reverse proxy, HAProxy for TCP/HTTP load balancing, and AWS Application Load Balancer via Terraform.

Nginx Configuration

• Generates complete server blocks with:
• Upstream groups with load balancing algorithms (round-robin, least_conn, ip_hash)
• Health checks (`max_fails`, `fail_timeout`)
• SSL termination with modern cipher suites and HSTS
• Gzip compression and static asset caching
• Rate limiting integration (`limit_req_zone`)
• Proxy headers (`X-Real-IP`, `X-Forwarded-For`, `X-Forwarded-Proto`)

HAProxy Configuration

• Frontend binds with ACL rules
• Backend server groups with health checks
• Stick-tables for session persistence
• Admin socket for runtime server management
• Stats page configuration

AWS ALB (via Terraform)

• ALB resource with security groups
• Target group with configurable health check path, interval, and thresholds
• HTTPS listener with ACM certificate ARN
• HTTP → HTTPS redirect listener
• Path-based and host-based listener rules
• Target group attachments for EC2 instances or ECS services

Advanced Patterns

• Blue-Green Switching — weighted target groups for gradual traffic shift
• Canary Deployment — 5% → 10% → 50% → 100% traffic migration rules
• Sticky Sessions — cookie-based affinity for stateful applications
