Eni

„ENI“ stands for „Elastic Network Interface“ in the context of cloud computing, specifically related to Amazon Web Services (AWS). An Elastic Network Interface is a virtual network interface that can be attached to an EC2 instance in a Virtual Private Cloud (VPC). It enables the instance to connect to the network, allowing communication with other instances, the internet, or on-premises networks.

ENIs can have multiple attributes, such as a primary private IPv4 address, one or more secondary private IPv4 addresses, and one or more public IP addresses. They provide a way to manage networking configurations that can be modified dynamically, including attaching and detaching network interfaces to instances without disrupting their operation. Additionally, ENIs support features like security groups and can be used for high availability and failover scenarios.

By utilizing Elastic Network Interfaces, users can enhance the flexibility and resilience of their network architecture within the AWS cloud environment.
