This image shows an on-premises Oracle Database deployment being migrated to a single-node VM DB System in Oracle Cloud Infrastructure.

• The on-premises data center contains an edge device for private connectivity to Oracle Cloud, an application server, and a 4-core Oracle Database Enterprise Edition installation connected to a storage device.
• The Oracle Cloud region contains a VCN with two private subnets, one for the application server and the other for the VM DB System.
• Security lists are used to regulate traffic to and from the subnets.
• Route tables are used to direct traffic bound for destinations outside the VCN.
• A Dynamic Routing Gateway enables private connectivity from the on-premises data center to the private subnets, using Oracle Cloud Infrastructure FastConnect or IPSec VPN.
• A Service Gateway enables the resources in the private subnets to communicate with Oracle Cloud Infrastructure Object Storage.
• RMAN is used to back up the on-premises database to Oracle Cloud Infrastructure Object Storage. Then, RMAN is used to restore the backed up database to a VM DB System.
