NIC card and vnet

Question

I am a newbie to Azure. I could see many resources in my azure with and without NIC card.

I have seen Data factory resource with NIC card and without NIC card. The only difference I could see is that, with NIC card I can apply NSG better.

My question is, at what point someone decide to create a NIC card for a resource (like data factory)

Thanks in advance

Hello Nikhil, Welcome to MS Q&A

Azure Data Factory typically doesn't require a Network Interface Card (NIC) since it's a managed service that operates without the need for direct network configuration like a Virtual Machine would. However, if you're working with scenarios involving Virtual Networks (VNets) or integrating with other Azure resources that do require NICs

Creating a Network Interface Card (NIC) for Azure resources, such as Data Factory, is typically necessary when you need to connect your resources to a virtual network. Here are some scenarios where you might consider creating a NIC:

• Virtual Machines: When setting up a virtual machine that requires connectivity to a specific virtual network and subnet.
• Multiple NICs: If you need to configure multiple NICs for a virtual machine to connect to different subnets.
• Network Security: To manage network traffic and security settings through network security groups associated with the NIC.

In the context of Azure Data Factory, if you're using a self-hosted Integration Runtime (IR) on a virtual machine, a NIC is needed to ensure that the VM can communicate with the Data Factory service and other Azure resources.

For more detailed information, you can refer to these resources:

• Azure Private Link for Azure Data Factory
• Virtual networks and virtual machines in Azure
• Create, change, or delete a network interface
