Simple GoLang Load Balancer

This is a simple load balancer implemented in GoLang designed to distribute incoming network traffic across multiple servers. It helps optimize resource usage, improves response times, and prevents overload on individual servers.

Features

• Round-robin Load Balancing: Distributes traffic evenly across multiple backend servers.
• Concurrency: Utilizes GoLang's goroutines to handle multiple requests concurrently for better performance.
• Customizable: Easily add or remove backend servers to suit the needs of your application.
• Basic Monitoring: Supports basic server health checks to ensure requests are routed to active servers.

Requirements

• Go 1.16 or higher
• Linux-based environment (recommended for real-world deployment)
• Basic understanding of GoLang and networking concepts

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/simplelb.git
   cd simplelb
   

2. Build the project:

   go build -o loadbalancer main.go
   

3. Run the load balancer:

   ./loadbalancer
   

   You can configure the backend servers by editing the servers slice in the main.go file.

Usage

• By default, the load balancer listens on port 8080 and distributes incoming HTTP requests to a predefined list of backend servers.
• You can add new backend servers by modifying the backendServers array in the main.go file.

Example Configuration

var backendServers = []string{
    "http://localhost:8001",
    "http://localhost:8002",
    "http://localhost:8003",
}
