A network interface enables an Azure Virtual Machine to communicate with the 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. Also, Network Interface Card (NIC) is assigned with an IP address and associated with NSG rules, which is used for communication between virtual machines or internal networks or the internet. The VM needs at least one NIC, NIC connects the VM to the VNet. One VM can have multiple NICs as well. In this article, I will show you how to Add or Remove Network Interface from a VM in Azure.
