This image shows an Oracle Cloud Infrastructure (OCI) region with Cloud Guard that contains an Availability Domain. The Availability Domain comprises three fault domains.

• Fault Domain 1 contains an HPC Node/NFS Server
• Fault Domain 2 contains an HPC Node/NFS Server, and a Bastion Host/Head Node. OpenFOAM is installed on the Bastion Host/Head node
• Fault Domain 3 contains an HPC Node/NFS Server

There is a Compartment A area illustrated with dotted lines that spans the Availability Domain. Compartment A is connected to a DRG, Nat Gateway, Internet Gateway, Service Gateway, and Object Storage.

There's a Virtual Cloud Network (VCN) area illustrated with dotted lines that spans the Availability Domain. Inside of the VCN, there is a Public Subnet and a Private Subnet.

• The Public Subnet is illustrated with dotted lines, and is connected to a Security List and Route Table. The Public Subnet spans the Availability Domain.
• The Private Subnet is illustrated with dotted lines, and is connected to a Security List and Route Table. The Private Subnet spans the Availability Domain. The Instance Pool, all HPC Nodes/NFS Servers are inside this Private Subnet.

There is a Customer Data Center outside of the Oracle Cloud Infrastructure Region. The Customer Data Center connects to IPSEC VPN or FastConnect, which then connects to the DRG (Compartment A).
