The OCI Region includes a four VCNs with three availability domains intersecting all four VCNs. Each VCN uses a services gateway (SG). The OCI region hosts policies, IAM, auditing, logging, and Object Storage.

- VCN-1 uses SG-1 and hosts a subnet with IP address 10.0.2.0/24 and the production environment.
- VCN-2 uses SG-2 and hosts a subnet with IP address 10.0.3.0/24 and the test environment.
- VCN-3 uses SG-3 and hosts a subnet with IP address 10.0.4.0/24 and the development environment.
