Have you worked with message broker systems?

Yes, experience with message exchange systems through brokers includes using technologies such as RabbitMQ, Apache Kafka, or ZeroMQ. These brokers provide asynchronous message exchange between system components, enabling the construction of scalable and fault-tolerant applications.

For example, in C++, you can use the ZeroMQ library to organize message exchange:

#include <zmq.hpp>
#include <string>
#include <iostream>

int main() {
    zmq::context_t context(1);
    zmq::socket_t socket(context, zmq::socket_type::req);
    socket.connect("tcp://localhost:5555");

    zmq::message_t request(5);
    memcpy(request.data(), "Hello", 5);
    socket.send(request, zmq::send_flags::none);

    zmq::message_t reply;
    socket.recv(reply, zmq::recv_flags::none);
    std::cout << "Received: " << reply.to_string() << std::endl;

    return 0;
}

This approach allows separating the sender and receiver of messages, improving the modularity and reliability of the system.
