The image shows various products and services connecting to Oracle Analytics Cloud located in an OCI region.

Google Analytics sends data directly to Oracle Analytics Cloud. Salesforce and eBay send data via a NAT gateway in the OCI region. The NAT gateway resides in a VCN and sends data to Oracle Integration, then on to Oracle Autonomous Data Warehouse (both in private subnet A), and then on to the Oracle Analytics Cloud.

On-premises solutions (SQL Server and other applications) send data bidirectionally via a CPE and site-to-site VPN to a DRG in the VCN. The DRG sends the data to Data Integration (in private subnet B), then on to the Oracle Autonomous Data Warehouse.

Flat files are sent to an Oracle Cloud Infrastructure Object Storage bucket within the OCI region, but outside the VCN, then on to Data Integration. Also, Oracle Fusion Service within the OCI region sends data to Data Integration.

Other services within the OCI region include: Oracle Cloud Infrastructure Identity and Access Management (IAM), Oracle Cloud Infrastructure Notifications, Oracle Cloud Infrastructure Audit, and email delivery.
