Open Source is in our DNA

When Cumulus was founded, virtually every data center was proprietary and engineers saw no other options. It was in this landscape that our company was born. Our mission remains to disaggregate every network so that businesses can leverage any software and hardware together. We believe this allows businesses to create better, faster networks.
