This image shows a region in Oracle Cloud Infrastructure (OCI) and a region in Microsoft Azure.

The Azure region shows a single availability zone and subscription that contains a customer virtual network (VNet) and an OCI child site that hosts Oracle Database@Azure.

The Azure VNet has an App subet that hosts the application and a delegated client subnet that provides a network interface to Oracle Exadata Database Service in an OCI virtual cloud network (VCN).

The OCI VCN is included in an OCI-managed network and spans the Azure and OCI regions. The VCN contains client and backup subnets that host Oracle Exadata Database Service. The VCN provides a service gateway to the control plane and OCI managed services in the OCI region including OCI-managed database backup that uses OCI Object Storage.
