The image shows a detailed architecture for Oracle Database@Google Cloud. It shows Google Cloud and an OCI Region.

Google Cloud which hosts an ODB network, Project A, and a default VPC. The default VPC hosts a zone with an Application subnet, which hosts an Application.

Oracle Database@Google Cloud hosts an OCI child site with a VCN which extends into the OCI Region. The VCN hosts a Client subnet with Oracle Autonomous Database and a Backup subnet with Oracle Exadata Database Service. The Client and Backup subnets share an instance of Oracle Exadata Database Service. Data travels between the Application in the Google zone and the Oracle Autonomous Database and Oracle Exadata Database Service. Oracle Database Autonomous Recovery Service exists in the Oracle Database@Google Cloud child site and uses the IP address of the Backup subnet.

The OCI Region hosts a Control plane, Object Storage, and OCI Vault.
