CC-Load-Balancer - Another Load Balancer Tool

This project is a custom implementation of a load balancer designed as part of a coding challenge here. The load balancer distributes incoming requests to multiple backend servers based on their health status. Docker is used to manage the load balancer and the backend servers.

Features

• Load balances requests across multiple backend servers.
• Performs health checks on servers and routes traffic only to healthy ones.
• Easy to configure and extend using a docker-compose.yml file.
• Command-line interface (CLI) for building, running, and testing using make.
• Supports automated testing of load balancer performance with curl.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• You need to have Go and Docker installed on your machine.
• Go version 1.15 or later is recommended.
• Docker and Docker Compose should be installed to manage services and containers.
• Make sure make is installed to run the commands from the provided Makefile.

Installing

Clone the repository to your local machine:

git clone https://github.com/nullsploit01/cc-load-balancer
cd cc-load-balancer

Building

You can build the project using the Makefile, which handles Docker image building for both the backend servers and the load balancer.

make build

Running

Once the images are built, you can start the load balancer and backend servers using:

make up

To stop the services, use:

make down

Testing

You can test the load balancer by making parallel HTTP requests to the load balancer, which will distribute them across the backend servers.

make test

Logs

You can view the logs for all services using:

make logs

Example Usage

Start the services and test the load balancer:

# Start the load balancer and backend servers
make up

# Test load balancing with parallel requests
make test

Stop the services when done:

make down
