How to configure virtual networks in the Azure portal

In this how-to video, we will show you how to configure an Azure virtual network, VNET, in Azure portal. This demo assumes that you are logging into the Azure portal with user credentials which have the minimum required permissions to create and configure an Azure VNET resource. This can be accomplished by using either a built-in or custom Azure RBAC role. Azure Virtual Network is a service that provides the fundamental building block for your private network in Azure. An instance of the service (a virtual network) enables many types of Azure resources to securely communicate with each other, the internet, and on-premises networks. These Azure resources include virtual machines, (VMs). A virtual network is similar to a traditional network that you'd operate in your own datacenter. But it brings extra benefits of the Azure infrastructure, such as scale, availability, and isolation. Azure virtual networks are Layer 3 overlays. Azure does not support any Layer 2 semantics, such as VLANs.You can however extend your on-premises subnets to Azure using a layer-3 overlay network based solution. You can also perform subnet delegation. Subnet delegation enables you to designate a specific subnet for an Azure PaaS service of your choice that needs to be injected into your virtual network.
