The image shows an OCI region with an availability domain with three fault domains: 1, 2, and 3, and OCI Kubernetes Engine spanning across the availability domain and three fault domains. A VCN spans across the availability domain and three fault domains, and contains two subnets: A and B. A web VM group and a database group span the three fault domains.

In subnet B, fault domain 2 contains OCI Load Balancer.

In subnet A:

The persistent volume claim has bi-directional connection to OCI File Storage via a network file system (NFS), and to the WebCenter Sites admin VM.

The load balancer connects to both the web VM group and database group.
