The image shows an Oracle Database@Google Cloud deployment integrated with Google Cloud and an OCI Region, all within an ODB network.

Google Cloud components include a Project with a VPC; a Region and Zone; an Application subnet hosting an application; and Cloud DNS.

Oracle Database@Google Cloud components include a VCN containing a Client subnet, an Oracle Database instance, a Network Security Group (NSG), and a Private DNS Listener Endpoint.

OCI components include a control plane for service management and OCI DNS for name resolution.

Traffic and control flows:

• Cloud DNS uses a DNS forwarding rule to send queries to the Private DNS Listener Endpoint.
• The Private DNS Listener Endpoint resolves names through OCI DNS.
• The application communicates privately with the Oracle Database within the VCN; access is governed by the NSG.
