Google is the Biggest Open-source Contributor to CNCF Projects: Stackalytics


Stackalytics data shows that Google is responsible for almost 53 per cent of all contributions across all Cloud Native Computing Foundation projects. Red Hat follows far behind with just 7.4 per cent


Google dominates all code contributions made across the Cloud Native Computing Foundation (CNCF) projects, according to the latest data from Stackalytics, an open source code analysis framework founded by Mirantis and hosted by the OpenStack Foundation.

The data showed that Google is responsible for almost 52.9 per cent of all code commits to CNCF projects. Red Hat follows far behind as the second biggest contributor, with only 7.4 per cent.

CNCF is an open source software foundation dedicated to making cloud native computing universal and sustainable. CNCF projects include Kubernetes, Prometheus, Envoy and a number of others.

Originally started as an open source project under the umbrella of the OpenStack foundation, Stackalytics used to focused exclusively on analyzing code contributions to OpenStack project. Now, it has expanded to encompass CNCF and a number of other independent popular projects, such as Istio, Spinnaker, OpenShift and more.

Even without Kubernetes, Google Dominates Code Commits

The CNCF is the home of Kubernetes, which originated in Google. But the Stackalytics data revealed that even without Kubernetes, Google remains the top code contributor to all CNCF projects.

“Many would assume that Google’s dominance over CNCF code contributions is because of its work in Kubernetes, but Stackalytics data reveals that this is not the case. In fact, it is GRPC, a Google dominated distributed queuing project that is still in CNCF incubation, that has the most all-time commits from Google, with Kubernetes in second place,” said Boris Renski, Co-Founder and CMO at Mirantis.

Surprisingly, Google’s third most active CNCF project is a little-known project called Vitess, a MySQL clustering for horizontal scaling. Vitess development is virtually exclusively on the shoulders of Google (or YouTube, from which it originated) with 77 per cent of commits.

Single company often the major contributor of individual projects

Mirantis also found that individual projects are frequently driven primarily by a single company. For example, FluentD – where 48 per cent of contributions comes from TreasureData; Jaeger – 64 per cent from Uber; LinkerD – 84 per cent from Buoyant; Notary – 61 per cent from Docker.

Interestingly, the only CNCF project with less than 40 per cent dominance by a single vendor is Prometheus, which was originally build by SoundCloud, but now virtually exclusively maintained by independent developers — and Red Hat.

Mirantis is the flexible infrastructure company harnessing open source to free application owners from operations concerns.
