# Arista vEOS
> Arista vEOS (Virtual Extensible Operating System) is a software-only instance of Arista's network operating system. It allows users to run the same EOS software found on physical switches within a virtual machine environment for testing, development, and network simulation. vEOS is designed to provide the exact same CLI, APIs, and features as hardware-based switches, excluding hardware-dependent ASIC features.
