Private VPN is an additional security feature which guarantees that your LPAR is on a network isolated from other logical partitions in the cloud. While the standard service provides strong security by isolation from Internet through VPN connection, it is possible that there may be multiple LPARs on the same network. The Private VPN option prevents this by placing your LPAR on a separate VLAN dedicated only to you. Nobody except the users assigned to your account can reach your logical partition.
Private VPN is a feature suitable for customers with strong security requirements who would like to reduce the exposure to security risks to minimum.
To take advantage of this enhanced security feature just select the Private VPN option when you order your AIX virtual machine.
