Description: The Elastic Network Interface (ENI) is a fundamental feature of Amazon Web Services (AWS) that allows users to create and manage virtual network interfaces within a Virtual Private Cloud (VPC). This interface can be attached to Amazon EC2 instances, providing a flexible and scalable network connection. ENIs are key components for cloud networking configurations, as they allow for the assignment of multiple IP addresses, the creation of private networks, and the implementation of security policies. Additionally, ENIs can be used to facilitate communication between different instances and services within the VPC, as well as to connect resources through Elastic Load Balancing and AWS Route 53. Their ability to be decoupled from EC2 instances allows for greater flexibility in network management, as they can be moved between instances as needed. In summary, the Elastic Network Interface is a powerful tool that enhances connectivity and network management in cloud environments, enabling organizations to design more complex and efficient network architectures.
