The image shows an Oracle region that contains a virtual cloud network and two private subnets (A and B) that all span a single availability domain. The region also contains an Oracle Fusion instance. The VCN contains an Object Storage instance. Within the availability domain, Subnet A contains an Autonomous Data Warehouse and an instance of Oracle GoldenGate. Subnet B contains a single Data Integration instance. Outside of the region are three third party data warehouses:

Traffic flows from the Oracle Fusion instance to the Object Storage instance via an Oracle Business Intelligence Cloud Connector (BICC). From there, it is directed to the Data Integration implementation, which then passes it to the ADW in Subnet A and then to the Oracle GoldenGate instance. Traffic passes from the Oracle GoldenGate instance, through a dynamic routing gateway out of the region to one of the three third-party data warehouses.
