Application Load Balancer with Round Robin Algorithm and Health Check

Overview

This Node.js project implements a simple application load balancer that uses a round-robin algorithm to distribute incoming requests among multiple target servers. Additionally, the load balancer performs health checks on the target servers to ensure that only healthy servers receive incoming traffic.

Features

• Round Robin Load Balancing: Incoming requests are distributed among target servers in a round-robin fashion, ensuring even utilization.

• Health Check: The load balancer performs periodic health checks on each target server to determine its availability. Unhealthy servers are temporarily excluded from the rotation.

• Multi-Process Setup: The load balancer can take advantage of multiple CPU cores using the Node.js Cluster module, creating separate worker processes for each core.

Requirements

• Node.js: Make sure you have Node.js installed on your machine. You can download it here.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/load-balancer.git

2. Navigate to the project directory:

   cd load-balancer

3. Install dependencies:

   npm install

Usage

1. Update the targets array in index.js with the details of your target servers.

2. Start the load balancer:

   npm start

3. Access your application through the load balancer at http://localhost:8000.

Configuration

• You can adjust the health check interval and other settings in the index.js file.
