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.

Read our open source philosophy to find out precisely where we stand in the open source community (that is, right in the heart and S.O.U.L. of it), view our regular contributions, and learn how we leverage open source.
