A simple load balancer

How does it work?

So, there is a simple TCP server that listens on a specific address (localhost:8080) and distributes incoming connections among a set of backend servers (localhost:5001, localhost:5002, localhost:5003). It includes basic setup for network communication, error handling, and connection acceptance.

The load balancing algorithm?

The program uses round-robin load balancing algorithm to select a backend server for each incoming connection, as indicated by the chooseBackend function call.

The purpose?

The purpose of this server is to act as a load balancer or proxy, distributing client requests evenly across multiple backend servers to manage load and ensure high availability.
