Load-Balancer

A Round-Robin based Load Balancer: Distributes requests to a list of servers in a cyclic order.

Installation

1. Clone the repository:

   git clone https://github.com/abhavgoel/Load-Balancer.git
   cd https://github.com/abhavgoel/Load-Balancer.git

2. Install dependencies:

   npm install

3. Configure the servers in index.js

   const servers = [
       { name: 'Server 1', port: 3001 , hostname: "localhost"},
       { name: 'Server 2', port: 3002 , hostname: "localhost"},
       { name: 'Server 3', port: 3003 , hostname: "localhost"},
   ];

4. Run the servers

   I have created a script to run the servers.

   ./run_servers.sh
   

   This would run your servers and the entry point server i.e. the load balancer.

You can access the load balancer at http://localhost:3000

Note: Remember when you run servers using the run_servers.sh script you wont be able to kill them using Ctrl + C. This is because in Unix systems background process are not terminated by Ctrl+C. So you can either kill then via terminal (by looking for process by ps -x command) or use the kill_servers.sh script. But keep in mind that this script will kill all processes that starts with "node" and ends with "js". It uses regex to find node processes from the ps -x command and kills them.
