On the other hand I do think it captures the common feeling of stepping on them in the dark barefoot... I think the fact that this question comes up over and over, almost like clockwork, is a clear signal that we (the community overall) still do not have a shared understanding of the answer, or some just don't like the stated answer and their change process is repeating the question hoping the answer changes. We've used the term 'cloud operating system' in various places, but not in our defining documents: * The Bylaws[0] use the phrase "the open source cloud computing project which is known as the OpenStack Project" * The TC charter[1] uses the phrase "one community with one common mission, producing one framework of collaborating components" * The UC charter [2] does not include a statement on "what is OpenStack" I've never liked the "cloud operating system" term because I felt it mis-represented how we defined ourself, but I've come to realize it may be the easiest-to-understand metaphor yet for what we are and where we are today. Going forward it is increasingly apparent that hybrid stacks (constellations, etc) will be common that include significant components that are not OpenStack at layers other than "layer 0" (ie, below all OpenStack components: database, message queue, etc). The example commonly given is of course Kubernetes, but there are others. UNIX caught on as well as it did partly because of its well-defined interfaces between components at user-visible levels, specifically in userspace. The 'everything is a file' metaphor, for all its faults, was simple to understand and use, until it wasn't. But to still serves us well. There was a LOT of 'differentiation' between the eventual commercial implementations of UNIX which caused a lot of pain for many (including me) but the masses have settled on the highly-interoperable GNU/Linux combination. (I am conveniently ignoring the still-present 'differentiation' that Linux distros insist on because that will never go away). [Thank you for reading this far, I didn't intend for this to be so verbose, but airport terminals can be quite boring at times :) ] This is where I see OpenStack today. We are in the role of being the cloud for the masses, used by both large (hi CERN!) and small (hi mtrienish's closet!) clouds and largely interoperable. Just as an OS (operating system)is the enabling glue for applications to function and communicate, our OS (OpenStack) is in position to do that for cloud apps. What we are lacking for guidance is a direct lineage to 20 years of history. We have to have our own discipline to keep our interfaces clean and easy to consume and understand, and present a common foundation for applications to build on, including applications that are themselves higher layers of an OS stack. Phew! Thank you again for reading this far, I know this is not news to a lot of our community, but the assumption that "everyone knows this" is not true, we need to occasionally repeat ourselves to remind ourselves and inform our newer members what we are, where we are headed and why we are all here in the first place: to enable awesome work to build on our foundation, and if we sell a few boxes or service contracts or chips along the way, our sponsors are happy too. dt [0] https://www.openstack.org/legal/bylaws-of-the-openstack-foundation/ [1] https://governance.openstack.org/tc/reference/principles.html#one-openstack -- Dean Troyer dtro...@gmail.com __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
