Python Load Balancer Example

Overview

This project demonstrates a simple load balancer using Python's built-in libraries. The load balancer uses the Round Robin algorithm to distribute client requests across multiple backend servers. It includes a load balancer, two backend servers, and a test client.

Requirements

• Python 3.6 or higher
• requests library

Setup Instructions

1. Clone the repository:

   • git clone https://github.com/lucasfonsecads/loadbalance-medium-example

   • cd load-balancer-example

2. Create and activate the virtual environment, and install dependencies:

   make install

Running the Components

Run Backend Servers

Open two separate terminal windows and run each server:

make server1

make server2

Run Load Balancer

In a third terminal window, run the load balancer:

make load_balancer

Run Test Client

In a fourth terminal window, run the test client to verify the load balancer:

make test

Run Everything Together

To run everything together in the same terminal:

make run_all

⁠This command will start both backend servers, the load balancer, and the test client sequentially, all in the same terminal.

Clean Up

To clean the virtual environment:

make clean

Explanation

• Load Balancer: Distributes client requests using the Round Robin algorithm.
• Backend Servers: Simple HTTP servers that respond with different messages.
• Test Client: Sends requests to the load balancer to verify that requests are being distributed correctly.
