# Load Balancer in Go

## About

A simple implementation in Go to better understand the working of a load balancer.

## Usage

Open up your terminal and run the following:

```bash

go run .

```

In another terminal window:

```bash

for i in {1..6}

do

curl http://localhost:8000

done

```

### Configuration

The `config.json` file looks something like this:

```json

{

  "lb": {

    "host": "localhost",

    "port": 8000

  },

  "servers": [

    {

      "host": "localhost",

      "port": 8001,

      "weight": 3,

      "uri": "http://localhost:8001"

    },

    {

      "host": "localhost",

      "port": 8002,

      "weight": 2,

      "uri": "http://localhost:8002"

    },

    {

      "host": "localhost",

      "port": 8003,

      "weight": 1,

      "uri": "http://localhost:8003"

    }

  ],

  "protocol": 0

}

```

#### Protocols

0: Weighted Round Robin (Just specify weight = 1 to all servers for Round Robin)

### Testing

To test the load balancer for race conditions:

```bash

go test -race

```

## TODO

1. Support for all methods (currently supports only GET & POST)

2. Dynamic Load Balancing algorithms
