  All external installations access Oracle Cloud Infrastructure through a NetFoundry SDN Network and an internet gateway into a single virtual cloud network (VCN).
• VCN: Provides a single private subnet, and an internet gateway for external traffic.
• Private subnet: Provides security list access and an Oracle Cloud Infrastructure Container Engine for Kubernetes node in each of the availability domains. Each node hosts a kubelet, proxy, pod, container and a pod network.
