Azure Virtual Network (VNet) is a fundamental element of Azure’s cloud infrastructure, offering a secure, isolated, and flexible networking environment for your cloud resources. As your infrastructure needs change, you may need to modify your VNet by adding subnets, creating and associating new network security groups.
This article walks you through the steps to update an Azure virtual network using the Azure portal.
