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

Google Cloud which uses an OCI managed network, hosts 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. The VCN hosts three subnets: Subnet with Oracle Autonomous Database, a Client Subnet, and a Backup Subnet. 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.

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