vgo-balancer

vgo-balancer is a Go-based load balancing solution designed to distribute network or application traffic across multiple servers efficiently. By using vgo-balancer, you can enhance the availability and reliability of your services, ensuring optimal performance and fault tolerance.

Features

• Efficient Load Distribution: Balances incoming traffic across multiple servers to prevent overload on a single server.
• High Availability: Ensures continuous service availability by redirecting traffic from failed or overloaded servers to healthy ones.

Installation

To install vgo-balancer, ensure you have Go installed on your system. Then, run:

go get -u github.com/rvarunrathod/vgo-balancer

Usage

1. Clone the Repository:

   git clone https://github.com/rvarunrathod/vgo-balancer.git
   cd vgo-balancer
   

2. Configuration:

   • Modify the config.yaml file to define your backend servers and load balancing preferences.

3. Build and Run:

   • To build the application:

     go build -o vgo-balancer cmd/main.go
     

   • To run the application:

     ./vgo-balancer
     

Configuration

The config.yaml file allows you to specify:

• Backend Servers: List of servers to distribute traffic to.
• Load Balancing Algorithm: Choose from available algorithms like round-robin, weighted-round-robin, ip-hash, least-response-time.
• Health Check Parameters: Define health check intervals and failure thresholds to monitor server health.

Docker Compose

If you have docker running in your local you can test there.

This command will build docker images for you,

docker compose build

And Run below command to run load balancer and servers

docker compose up

Benchmarking

A benchmarking script is included in the tools/benchmark directory. Run it with:

cd tools/benchmark && go run main.go -url http://localhost:8080 -c 10 -n 1000 -d 10s

Available flags:

• -url: Target URL (default: "http://localhost:8080")
• -c: Number of concurrent requests (default: 10)
• -n: Total number of requests (default: 1000)
• -d: Duration of the test (e.g., "30s", "5m")
