This image shows an Oracle Cloud Infrastructure region that provides object storage for the region. The region includes a single availability domain with two fault domains. The availability domain provides file storage for the availability domain. The availability domain includes a virtual cloud network (VCN) with four regional subnets with routing tables and security lists for each subnet. The VCN includes the following gateways:
  • A dynamic routing gateway (DRG) for private connections from the customer's data center through IPSec VPN or FastConnect to the bastion and load balancing subnets.
  • An internet gateway for user connections to the load balancing subnet.
  • A network address translation (NAT) gateway for user connections to the applications layer and database subnets.
  • A Service gateway to connect the VCN to object storage services.

The regional subnets are arranged as functional layers:
