How to Create internet-facing Network(TCP) layer load balancer on Google Cloud Platform.

Google Cloud external TCP/UDP Network Load Balancing (after this referred to as Network Load Balancing) is a regional, pass-through load balancer. A network load balancer distributes TCP or UDP traffic among virtual machine (VM) instances in the same region.

A network load balancer can receive traffic from:

  1. Any client on the internet
  2. Google Cloud VMs with external IPs
  3. Google Cloud VMs that have internet access through Cloud NAT or instance-based NAT.
