How Does Virtual Networking Work?

Virtual networking works by abstracting network hardware and functionality into software. Instead of relying on physical switches, routers, and cables, virtual networking software creates and manages virtual versions of these components.

This software layer sits on top of the physical network infrastructure and controls how data flows between virtual machines, containers, or other virtual endpoints. It uses techniques like network virtualization and software-defined networking (SDN) to create isolated virtual networks that can share the same underlying physical hardware.

Data traffic is routed and managed by these virtual components, allowing for flexible configuration, dynamic resource allocation, and simplified network management. Essentially, virtual networking creates a software-defined layer that overlays the physical network, enabling the creation and management of multiple independent and customizable networks without requiring changes to the physical infrastructure.
