The image shows an Azure region containing a subscription, a container registry, and two availability zones (1 and 2).

An application VNet spans both availability zones, and contains a load balancer and AKS.

Availability zones 1 (primary VNet database) and 2 (secondary VNet database) each contain a client subnet with Oracle Database@Azure.

The OCI region contains OCI managed services: two instances of Oracle Database Autonomous Recovery Service, and one of OCI Vault. Oracle Database@Azure is automatically backed up to Oracle Database Autonomous Recovery Service.

OCI manages the network between the Azure region and the OCI region.

The primary route has a DNS outside of these regions connecting to the load balancer, and along to the AKS, which connects toOracle Database@Azure in the primary VNet database, and to the container registry.

The primary database backs up data to Oracle Database Autonomous Recovery Service, stores encryptino keys in OCI Vault, and replicates data to the standby database using Oracle Data Guard or Active Data Guard via the OCI managed network. The standby database backs up data to Oracle Database Autonomous Recovery Service and stores encryption keys in OCI Vault. The AKS connects to the primary Oracle Database@Azure via VNet peering.
