Load Balancer Challenge

This project is a simple implementation of a load balancer and backend servers.

Prerequisites

• Python 3.x

How to Run

1. Clone the repository to your local machine.
2. Navigate to the project directory in your terminal.
3. Run the backend servers. You can start a servers on a multiple ports by running python3 start_be_servers.py. You can configure details for the instances in config.json.
4. Run the load balancer by running python3 lb.py.

How to Test

1. Send a request to the load balancer from a separate terminal window. You can do this by running curl localhost:<load_balancer_port>.
2. The load balancer should forward your request to one of the backend servers and then forward the server's response back to you.

Technical Details

Round-Robin Load Balancing

The load balancer utilizes a round-robin algorithm to evenly distribute incoming requests among the available servers. This ensures each server gets an equal share of the load, preventing any single server from becoming a bottleneck.

For a detailed reflection on the development process and key learnings from this project, check out LearningExperience.md.
This is a basic implementation of a load balancer and does not include many features that a real-world load balancer would have, such as health checks, session persistence, and SSL termination.
