This document discusses using Arista networking solutions to scale cloud computing networks. It presents two use cases: 1) using OpenStack with the ML2 plugin for network virtualization, and 2) using an SDN controller with OVSDB for network abstraction. For use case 1, it demonstrates how CloudVision Exchange integrates with OpenStack Neutron to provide network automation, visibility, and improved scaling through VXLAN hardware VTEPs and an L3 ECMP fabric. For use case 2, it shows how CloudVision Exchange abstracts the network topology to allow adding bare metal servers and VXLAN gateways through an SDN controller using OVSDB.
