What
is Azure Virtual Network?
Azure Virtual Network (VNet) is the fundamental building
block for your private network in Azure. VNet enables many types of Azure
resources, such as Azure Virtual Machines (VM), to securely communicate with
each other, the internet, and on-premises networks.
VNet
concepts
Address
space: When creating a VNet, you must specify a custom private
IP address space using public and private (RFC 1918) addresses. Azure assigns
resources in a virtual network a private IP address from the address space that
you assign. For example, if you deploy a VM in a VNet with address space,
10.0.0.0/16, the VM will be assigned a private IP like 10.0.0.4.
Subnets:
Subnets enable you to segment the virtual network into one or more sub-networks
and allocate a portion of the virtual network's address space to each subnet.
You can then deploy Azure resources in a specific subnet. Just like in a
traditional network, subnets allow you to segment your VNet address space into
segments that are appropriate for the organization's internal network. This
also improves address allocation efficiency. You can secure resources within
subnets using Network Security Groups. For more information, see Security
groups.
Regions:
VNet is scoped to a single region/location; however, multiple virtual networks
from different regions can be connected together using Virtual Network Peering.
Subscription:
VNet is scoped to a subscription. You can implement multiple virtual networks
within each Azure subscription and Azure region.
