Description: A virtual network interface is a software-based solution that allows virtual machines to connect to a network, facilitating communication between them and with other devices in the network infrastructure. This interface acts as a bridge between virtual machines and the physical network, allowing virtualized instances to behave as if they were physical devices on the network. Virtual network interfaces are fundamental in virtualization environments, as they enable network segmentation, traffic management, and the implementation of security policies. Additionally, they are essential for creating software-defined networks (SDN), where network configuration and management are performed through software rather than hardware. These interfaces can be configured to support different network protocols and can be used in various virtualization platforms, such as KVM, VMware, and Microsoft Hyper-V, as well as in cloud solutions like Azure and AWS. Their flexibility and adaptability to different network environments make them a key tool for modernizing IT infrastructures and optimizing cloud resources.
