Go Load Balancing Reverse Proxy

A high-performance reverse proxy implementation in Go with advanced load balancing capabilities and YAML-based configuration.

Features

• Configurable load balancing strategies
  • Round-robin (implemented)
  • Random selection (planned)
  • Least connections (planned)
• Health checks for backend servers
• Connection pooling and timeout management
• Extensive metrics collection
• Comprehensive logging system
• YAML-based configuration

Configuration

The proxy is configured using config.yml. Example configuration:

servers:
  - address: "127.0.0.1:9091"
    timeout:
      connect: 5s
      read: 10s
      write: 10s

load_balancer:
  strategy: "round-robin"
  health_check:
    interval: 5s
    timeout: 2s
    retries: 3

Getting Started

1. Clone the repository:

git clone https://github.com/Ameriq8/reverse-proxy.git
cd reverse-proxy

2. Configure your backend servers in config.yml

3. Run the proxy:

go run main.go

Requirements

• Go 1.16 or higher
• YAML configuration file

TODO List

High Priority

  • Random selection
  • Least connections
  • IP hash-based routing
• TLS support
• Request/response middleware
• Rate limiting
• Circuit breaker implementation

Low Priority

• Admin REST API
• Monitoring dashboard
• Service discovery integration
• Caching layer
• WebSocket support
