Azure Virtual Network Description
Azure Virtual Network provides a secure environment for virtual machines and applications. You can use your private IP addresses to create subnets, access control policy, and other configurations. Virtual Network allows you to treat Azure as you would your datacenter. Traffic between Azure resources in one region or multiple regions stays in the Azure network. Intra-Azure traffic does not flow over the Internet. Traffic for virtual machine-tovirtual machine, storage and SQL communication in Azure only flows through the Azure network. This is regardless of where the destination Azure region is. Traffic from inter-regional virtual networks to virtual networks flows completely over the Azure network. Virtual Network allows you to extend your IT environment on-premises into the cloud. It works in the same way as connecting to a remote branch office. There are two options for securely connecting to a virtual network: an IPsec VPN or private connection using Azure ExpressRoute.
