Golang Load Balancer

This is a Load Balancer implemented in Golang that distributes incoming traffic across multiple backend servers. The load balancer supports different load-balancing strategies and ensures high availability and fault tolerance for backend services.

Features

• Least Connections: Routes traffic to the server with the fewest active connections.
• Health Checks: Periodically checks the health of backend servers and removes unhealthy ones from the rotation.
• High Availability: Routes traffic only to available and healthy servers.
• Logging: Provides logs for monitoring traffic distribution and backend health.

Prerequisites

To run this project, you'll need:

• Golang (version 1.16 or above)

Installation

1. Clone the repository:

   git clone https://github.com/itpourya/go-loadbalancer.git
   

2. Navigate to the project directory:

   cd go-loadbalancer
   

3. Install the dependencies:

   go mod tidy
   

Configuration

1. Open the internal/example file (if applicable) and configure your backend servers with python Flask:

Running the Load Balancer

To start the load balancer:

go run cmd/main.go

The load balancer will start and listen for incoming traffic, forwarding requests to available backend servers according to the specified algorithm.

Health Checks

The load balancer periodically checks the health of backend servers by sending HTTP requests. Unhealthy servers are automatically removed from the rotation until they recover.

Project Structure

• main.go: The entry point of the load balancer.
• internal/loadbalancer/: Contains the logic for different load balancing strategies.
• internal/health/: Manages health checks for backend servers.
