Connectivity in Azure
The fundamental building block of your network in Azure is Azure Virtual Networks or VNets, as we will refer to from now on. VNets allow organizations to build networks as if they were on-premises. Think of VNets as the primary component for availability and isolation purposes.
On top of VNets, you can configure and manage Virtual Private Networks or VPNs and connect with other VNets across the various regions available in Azure and extend your on-premises network. Similar to an on-premises network, each VNet has its own Classless Inter-Domain Routing or CIDR block, and they can be connected with other VNets as long as their CIDR blocks don’t overlap.
Similar to on-premises networks, TCP, UDP, and ICMP TCP/IP protocols are supported within VNets.
Now we will discuss how you can start designing your virtual networks in Azure.
Design considerations for VNets
Before creating a VNet, consider using address ranges enumerated in RFC 1918 to facilitate...
