The image shows a network connection between an OCI region and Google Cloud. The OCI region hosts a VCN containing two subnets, each with its own NSG. The OCI VCN connects to a DRG. The DRG connects to Google Cloud using either FastConnect and Google Cloud Interconnect.

The Google Cloud region hosts a VPC containing a region and a zone with two subnets; Subnet C and Subnet D. The connection from OCI to Google Cloud passes through a Google Cloud Router, which provides routing between the two cloud environments.
