The image shows an architecture having an OCI Region with a single VCN having a private subnet: Private Subnet A. The VCN spans across and availability domain named Availability Domain 1.

The OCI Region hosts Oracle Fusion Cloud Applications which uses BICC to connect and load data into Object Storage inside the VCN.

OCI Data Science is hosted inside Private Subnet B within the availability domain and Object Storage connects to it.

Snowflake Data Warehouse is hosted outside the OCI Region. Amazon Simple Storage Service (S3), Google Cloud Storage, and Azure Stroage all connect to the Snowflake Data Warehouse and can be used to load data into it.
