An Azure virtual network (VNet) is a representation of your own network in the cloud. It is a logical isolation of the Azure cloud dedicated to your subscription. You fully control the IP address blocks, DNS settings, security policies, and route tables within this network. You can also further segment your VNet into subnets and deploy Azure IaaS VMs to use Teradata Database products. Additionally, you can connect the VNet to your on-premises network.
When you deploy Teradata Database products in Azure using a solution template, private IPs are assigned within the same VNet or VNet peering. After deploying a solution template, you have the option to create public IPs if you are connecting to the public cloud through the Internet.
When you deploy Teradata Database products separately, you can create a new or select an existing public IP address.
VNets are associated to a resource group which provides network boundaries for resources. A VNet is required when deploying a VM. VNets cannot span over multiple regions.
