The image shows ReadyNetworks' hybrid model architecture on Oracle Cloud Infrastructure (OCI). In the hybrid model, the entire infrastructure is secured and isolated within the customer's tenancy.

The OCI region provides 1 availability domain, 3 fault domains, and a single customer compartment. The region provides the following services:

• Oracle Cloud Infrastructure Audit
• Oracle Cloud Infrastructure Backup and Restore
• Oracle Cloud Infrastructure File Storage
• Oracle Cloud Infrastructure Logging
• Oracle Cloud Infrastructure Object Storage
• Oracle Cloud Infrastructure Tagging
• Oracle Cloud Infrastructure Vault

The customer compartment: Includes 1 VCN with the following gateways:

• Internet gateway: Provides communications between public subnets and internet hosts. RDP traffic uses the internet gateway.
• Service gateway: VCNs communicate with services such as object storage over the Oracle network fabric without traversing the internet.

The VCN provides 2 private subnets each with its own security list and route table.

• Six.One portal private subnet: The subnet includes encryption, a flex virtual machine (VM) and, optionally, active directory in fault domain 1. Fault domain 2 includes the Six.One portal, encryption, a persistent volume, and a flex VM that functions as an RDP gateway proxy server.
• VDI private subnet: Includes encryption, a persistent volume and a flex VM in fault domain 2.
