Apstra Operating System (AOS) is a turnkey application for automating the lifecycle of data center leaf-spine network services. AOS works with your established vendor switch hardware (Cisco, Juniper, Arista, Mellanox) and your switch operating systems (NX-OS, Junos, EOS, Cumulus), brite-box (Dell EMC) or white-box hardware running a variety of switch operating systems including Cumulus and open alternatives (Microsoft SONiC, Dell EMC OpenSwitch OPX). AOS helps you automate your network as a single system, not as complex individual parts. AOS completely decouples your network design, implementation and operations from the physical (underlay) and virtual (overlay) network infrastructure, using whichever hardware and switch OS you choose.
