GoScale

GoScale is a versatile load balancing application written in Go that provides various algorithms for distributing incoming traffic among backend servers. It supports the following algorithms:

• Round Robin (RR)

• Weighted Round Robin (WRR)

• Least Connections

• Least Time

Features

• Dynamic Routing: GoScale dynamically routes incoming requests to healthy backend servers based on different load balancing algorithms.

• Health Checking: It regularly checks the health of backend servers and excludes unhealthy servers from the routing pool.

• Algorithm Options: Users can choose from multiple load balancing algorithms to optimize traffic distribution based on their specific requirements.

• Configuration: GoScale can be easily configured via a JSON file, allowing users to define backend servers, their weights, and other settings.

• Docker support for easy deployment and scalability.

• HTTP Keep-Alive Support: GoScale implements HTTP Keep-Alive to reuse backend connections until the timeout expires, improving performance and reducing latency.

Usage

Installation

To install GoScale , you need to have Go installed. Then, you can clone the repository and build the application using the following commands:

git clone https://github.com/lokesh-katari/GoScale
cd GoScale
go build -o goscale cmd/main.go

or

To use GoScale, simply pull the Docker image from Docker Hub:

docker pull lokeshkatari/goscale

Then, create a config.json file to configure the backend servers, their weights, and the load balancing algorithm. Finally, run the Docker container:

docker run -v /path/to/config.json:/app/config.json -p 8082:8082 lokeshkatari/goscale:latest

Configuration

GoScale is configured via a config.json file. You can specify the backend servers, their weights, the load balancing algorithm, and other settings in this file.

{
  "servers": [
    {
      "url": "http://localhost:8081",
      "weight": 2
    },
    {
      "url": "http://localhost:8082",
      "weight": 1
    }
  ],
  "algorithm": "WeightedRoundRobin",
  "proxy": "http://localhost:8080"
}
