The image shows a Primary Region and a Standby Region. Both regions are identical, except the Standby Region contains RackWare deployed on a Private Subnet.

Within both regions there is a virtual cloud network (VCN) connected by an Internet Gateway and Network address translation (NAT) Gateway. Inside the VCN is a Container Engine for Kubernetes. There is an Application Replication arrow connecting both Container Engine for Kubernetes. Inside the Container Engine for Kubernetes, there is a Public Subnet and Private Subnet. The Public Subnet contains a Load Balancer, while the Private Subnet contains a Container Engine for Kubernetes Node.

Outside of the VCN area, both regions contain an Oracle Cloud Infrastructure Registry(OCIR). Both OCIRs are connected with OCIR Replication.
