The image shows an on-premises region, OCI region 1, OCI region 2, and three partner regions: Microsoft Azure with Azure Blob Storage, AWS Cloud with Amazon S3, and Google Cloud with Google Cloud Storage.

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

OCI region 1 contains a virtual cloud network (VCN) 1 has a public subnet A, a private subnet A, and OCI Object Storage.

Public subnet A contains an OCI Bastion instance. Private subnet A has an integration compartment with Oracle Integration, an OCI virtual machine, and OCI Data Integration.

OCI region 2 contains VCN 2 with private subnet 2, which has an Oracle Autonomous Data Warehouse.

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 has a bi-directional connection using remote peering to a DRG in VCN 2.

A user outside of the OCI region connects to public subnet A through an internet gateway in VCN 1.

Private subnet A's integration compartment connects to private subnet B's Oracle Autonomous Data Warehouse.

A security gateway in VCN 2 connects to a security gateway in VCN 1, then to OCI Object Storage. From there, it either connects to Microsoft Azure using OCI FastConnect and Azure ExpressRoute; to AWS Cloud using OCI FastConnect and AWS Direct Connect; or to Google Cloud using OCI FastConnect and Google Partner Interconnect.
