A network interface is a logical networking component in a VPC that represents a virtual network card. A network interface is assigned an IP address either automatically or manually based on its subnet. After you deploy an Amazon EC2 instance in a subnet, you can attach a network interface to it, or detach a network interface from that Amazon EC2 instance and reattach to another Amazon EC2 instance in that subnet. The device index identifies the position in the attachment order.
