Loadbalancer

This is a very simple loadbalancer written in Go

---

A little hobby project to familiarize myself with Go

Usage

The loadbalancer simply needs a yaml config file like this:

loadbalancer:
  inProduction: false
  backendServers:
    - "http://localhost:8082"
    - "http://localhost:8083"
    - "http://localhost:8090"
  startGivenServers: true
  port: 8080
  schedulingAlgorithm: "round-robin"

Download

Download the latest version of loadbalancer here

It's currently being built for Linux and MacOS

Download the one suited for your system, extract the tarball and run it.

Example with the above stated loadbalancer.yaml

./loadbalancer start --config ~/loadbalancer.yaml

• The loadbalancer will now start on port 8080
• It will fire up the webservers as dummy backend servers because we set startGivenServers to true
• It will use the round-robin mode to choose the next server to go to for each request
• Hit http://localhost:8080/ in your browser and you should see a a response from the next backend server on every refresh

Loadbalancer algorithms

Currently the following options for loadbalancing are:

• round-robin
