NIC

• NIC => network interface card
• A network interface card (NIC) is the interconnection between a VM and a virtual network (VNet)
• A VM must have at least one NIC (can have more than one, depending on the size of the VM)
• Each NIC attached to a VM must exist in the same location and subscription as the VM
• A NIC must be connected to a VNet that exists in the same Azure location and subscription as the NIC
• A network interface enables an Azure Virtual Machine to communicate with internet, Azure, and on-premises resources
• When creating a virtual machine using the Azure portal, the portal creates one network interface with default settings for you

Prerequisites of creating NIC

• Before creating a network interface you must have an existing virtual network in the same location and subscription you create a network interface in
• The portal doesn’t provide the option to assign a public IP address to the network interface when you create it (If you want to create a network interface with a public IP address, you must use the CLI or PowerShell to create the network interface)
• Public IP address can be assigned to the network interface after creating it

Create Resource Group:

• Go to: https://portal.azure.com/#create/Microsoft.ResourceGroup (login to Azure portal first, then click the link)
• Fillup details (i.e. name ‘demo-rg’, select subscription etc.)
• Create

Create required resource:

• Create VNet

Creating NIC using Azure portal

• Go to: https://portal.azure.com/#create/Microsoft.NetworkInterface-ARM (login to Azure portal first and then click the link)
• Fillup details (resource group, name, VNet, subnet, NSG etc.) > Next
• Add tags > Next
• Create

Associate public IP address

• Go to resource groups: https://portal.azure.com/#blade/HubsExtension/BrowseResourceGroups
• Select resource group > select target NIC
• Settings: IP configurations > Click existing config i.e. ‘ipconfig1’ (or ‘+ Add’ if you want to add new)
• Associate > Save
