Here’s how you can add insight and context to this ongoing effort.


OpenStack grew out of the belief that a community of equals, working together in an open collaboration, would produce better software. That software would be more aligned meet to the needs of its users and, in turn, be more largely adopted.

At the most recent Summit in Berlin, a book called the Four Opens was launched.
They are:

  • Open source
  • Open design
  • Open development
  • Open community

After eight years, the Four Opens have proved pretty resilient, consistently managing to capture the OpenStack way of doing upstream open source development. They are instrumental in the success, the quality and the visibility of the OpenStack software.

Earlier this year, the OpenStack Foundation started the Four Opens Book as a way to share these learnings and how the Four Opens were initially intended for upstream as well as how they proved applicable to downstream activities such as user feedback gathering, marketing, or event management.

As the OpenStack Foundation grows to more generally support open infrastructure, the Four Opens will grow alongside it.

The effort was spearheaded by Chris Hoge, strategic program manager at the OSF, who wants to underline that you’re still welcome to contribute and share your open source learnings as this book continues to evolve and reflect community values. Hoge tells Superuser he’s especially interested in contributions outlining how the 4Os are being applied in practice.
