The image shows end users using the internet to access an internet gateway within an OCI Region. The OCI Region is comprised of one availability domain, and within the availability domain are two fault domains.

A virtual cloud network and two private subnets span both fault domains. The first fault domain contains one load balancer, one primary node, and two secondary nodes. The second fault domain contains no architecture components. Traffic flows from the internet gateway (outside of the availability domain) into the load balancer, into the primary node, separating into two separate secondary nodes.
