What is Eni used for?

An elastic network interface is a logical networking component in a VPC that represents a virtual network card. It can include the following attributes: A primary private IPv4 address from the IPv4 address range of your VPC. One or more IPv6 addresses.
How many Eni is an instance?
large instance may have up to three ENIs attached to it. The primary network interface for the instance counts as one, so you can attach an additional two ENIs to the instance. Because each task using the awsvpc network mode requires an ENI, you can typically only run two such tasks on this instance type.
How many IPs is an Eni?
One Elastic IP address per private IPv4 address. One public IPv4 address, which can be auto-assigned to the network interface for eth0 when you launch an instance. One or more IPv6 addresses. One or more security groups.

Why do we need AWS Eni?
Essentially, ENIs are virtual network cards you can attach to your EC2 instances. They are used to enable network connectivity for your instances, and having more than one of them connected to your instance allows it to communicate on two different subnets.
What is Lambda Eni?
The Hyperplane ENI is a managed network resource that the Lambda service controls, allowing multiple execution environments to securely access resources inside of VPCs in your account.
Can we attach multiple Eni to EC2?
ENI — Key Features You can create an attach an additional/ secondary ENIs to an instance in your VPC. A Security Group is attached to an ENI not an EC2 instance. With this approach you can have multiple routes to the same EC2 instance with different security configurations.
