The image shows on-premises resources and an OCI region.

The on-premises zone contains a user, databases, applications, and customer-premises equipment.

The OCI region contains a virtual cloud network (VCN) 1 with a public subnet A, and a private subnet A, and a second VCN (VCN 2) with a private subnet B. The region also includes Oracle Services Network (OSN).

VCN 1's public subnet A contains an OCI Bastion instance; and it's private subnet A contains a data integration compartment with an OCI virtual machine and OCI Data Integration. VCN 2's private subnet B contains Oracle Autonomous Data Warehouse.

OSN contains OCI Object Storage, Oracle Integration, and Oracle Analytics Cloud.

The customer-premises equipment has a bi-directional connection using OCI Site-to-Site VPN to a Dynamic Routing Gateway (DRG) in VCN 1. That DRG also connects to VCN 2.

A user connects to the public subnet A through an internet gateway in VCN 1.

Private subnet A's data integration compartment connects to the Oracle Autonomous Data Warehouse which connects to Oracle Integration and Oracle Analytics Cloud in OSN. A user outside of the OCI region also connects to Oracle Analytics Cloud.

OCI Object Storage has bi-directional connects to service gateway 1 (SG1) in VCN 1, and to SG2 in VCN 2.
