Virtual Network
A logically isolated private network in Azure (VNet) that connects Azure resources securely.
Azure Virtual Network (VNet) provides a logically isolated private network where Azure resources such as virtual machines communicate without traffic crossing the public internet. Administrators segment a VNet into subnets, control routing with route tables, and enforce traffic rules using Network Security Groups at the subnet or NIC level. A common exam confusion is treating VNet peering and VPN Gateway as interchangeable. VNet peering connects two VNets privately over Microsoft’s backbone with no gateway needed, while VPN Gateway encrypts traffic over the public internet, typically connecting an on-premises network to Azure. These are distinct solutions for distinct scenarios.
