The image illustrates the deployment of a VDI environment with Oracle Exadata Database Service in OCI. In this diagram, a customer data center and threeremote facilities use client VPNs to access a VCN within an OCI region. The VCN contains these five subnets:

A VPN and load balancer subnet, containing a firewall and an application load balancer. Access to this subnet is controlled by a routing table and a security list.
A virtual desk infrastructure subnet, containing:
- A bastion server.
- A VDI license proxy.
- Three VDI server clusters.
Access to this subnet is controlled by a routing table and a security list.
A client desktop subnet, containing:
- An NSX managed network overlay.
- A flex VM.
- A bustable VM.
- A VM with a GPU.
- A second VM.
Access to this subnet is controlled by a routing table and a security list.
A database subnet containing an Exadate database.
A service subnet containing:
- OCI object storage backups.
- A storage gateway.
- Home directory file storage.

Data travels bidirectionally through all of these subnets.

The customer data center can connect to the VCN over either a client VPN or through custromner premises equipment over FastConnect and through a dynamic routing gateway. Traffic can also flow between the VPN and load balancer subnet and the DRG over a site-to-site VPN and then through an Internet gateway.
