Google Cloud Platform (GCP) offers Internal Load Balancing for your TCP/UDP-based traffic.

Internal Load Balancing enables you to run and scale your services behind a private load balancing IP address that is accessible only to your internal virtual machine instances.

Use Internal Load Balancing to configure an Internal Load Balancing IP address to act as the frontend to your private backend instances. You do not need a public IP for your load balanced service. Your internal client requests stay internal to your VPC network and region, likely resulting in lowered latency since all your load-balanced traffic will stay within Google's network. Overall, your configuration becomes simpler.
