# Layer 4 (TCP) Load Balancing Configuration

stream {

    upstream tcp_backend {

        # Define backend servers for TCP load balancing

         server backend1.example.com:80 weight=3;  # Backend 1 (higher weight)

         server backend2.example.com:80 weight=1;  # Backend 2

    }

    # TCP Load Balancer listening on port 80

    server {
