Ferrugem Load Balancer

A lightweight and efficient load balancer implemented in Rust.

Overview

This project is a load balancer built using the Rust programming language and the Axum web framework. It is designed to be efficient and lightweight, capable of distributing incoming HTTP requests across multiple backend servers.

Features

• Efficiently handles incoming HTTP requests and routes them to backend servers.
• Logs incoming requests and responses for easy debugging and monitoring.
• Configurable logging levels to control the amount of logged information.
• Utilizes the reqwest library for making HTTP requests to backend servers.
• Thread-safe, using tokio::sync::Mutex for state management.
