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

The on-premises resources include a user, databases, applications, and customer-premises equipment.

OCI region 1 contains a virtual cloud network (VCN) 1 with a public subnet A, a private subnet A, and Oracle Services Network (OSN) containing OCI Object Storage.

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

OCI region 2 contains VCN 2 with private subnet 2, which hosts Oracle Autonomous Data Warehouse. Region 2 also has OSN, with an Oracle Integration instance.

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

A secure gateway (SG2) in VCN 2 connects to SG1 in VCN 1, then to OCI Object Storage. OCI Object Storage is connected using OCI FastConnect and Azure ExpressRoute to Microsoft Azure including Azure Blob Storage; using OCI FastConnect and AWS Direct Connect to AWS Cloudincluding Amazon S3; and using OCI FastConnect and Google Partner Interconnect to Google Cloud including Google Cloud Storage.
