Elastic Network Interface
Get a working knowledge of the elastic network interface in EC2.
We'll cover the following...
Communication between different network elements relies on the network interface, a component designed to communicate over the network. Each server requires a network interface to be a part of a network. A network interface has two different addresses: Private IP to communicate within the network and Public IP for outside the network. Similarly, in AWS, the communication of EC2 instances depends on the Elastic network interface. In this lesson, we will learn about the Elastic network interface in detail and explore how it works with an example.
What is ENI?
An Elastic Network Interface (ENI), also known as a Network Interface, is a virtual network card that can be attached to the EC2 instances. ENI is a logical networking component that can be used to provide multiple IP addresses or attach an instance to different subnets. An Elastic Network Interface (ENI) in AWS is ...
