A fair point. One thing worth remembering is that this was a point in time thing. I have seen a lot of movement and some very positive signals around convergence of OpenStack, and a real focus on the end user community. When I was doing the digging things felt different and there is a decent chance that were open stack where it is now I would have taken a different position.

The mission of CNCF is the promotion of 'cloud native technologies' -- specifically container packaged, dynamically scheduled, micro-services oriented workloads. It isn't about picking winners, it is about establishing a safe space for innovation and bringing to bear the collective communities. We have legitimately taken some time in getting the identity of the foundation established, but I feel like Dan Kohn (our new ED) is doing super work in creating a collaborative space for new projects.

Thanks for the part of the response though I'm still concerned at the 'felt' part though, especially if that felt part didn't involve talking with much/any(?) of that community in a public forum. Is there anything I can do to help you understand it better, I'd at least like to be able to echo whatever concerns you had to that community, because at that point it can be actual data that made the decision to go with CNCF creation and not just feelings or thoughts of movement or positive signals (all very fluffy things IMHO).

So in the CNCF, are competing implementations allowed / encouraged?

For me that would have repercussions for what other tech a CNCF project supports (e.g. is all stats monitoring based on Prometheus, or can 2 projects in the CNCF support different technologies)

Hi, I'm alexis richardson and chair of the TOC for CNCF. The answer is YES we allow competing implementations.

to elaborate for @hueving @mugsie et al., consider that OpenStack is organised around Nova, the scheduler++ that is at the heart of any OpenStack deployment. If the CNCF was "like OpenStack" then it could mandate that all projects are organised around Kubernetes, playing a role analogous to Nova. But we didn't want to be solely a "Kubernetes foundation". The market is early stage, and there are other valid approaches to orchestration, including Docker Swarmkit, Hashicorp Nomad, Mesos & DCOS templates like Marathon, and others. So, we need a different approach.

Of course there are people who want a KubeStack that is like OpenStack, for better or worse. That's fine too! We just don't want that to be the ONLY choice for customers.

Do you allow competing APIs for the same service? If not, how is that any different from OpenStack? If so, how do you address the issue of fragmentation across deployments?

Yes we do allow competing APIs.

You said it yourself in another comment on here: "It's never blatant, it's always calls for seemingly good things like extra pluggable points to make sure we don't favor particular solutions. Then it's making sure that any decision is brought to a huge vote by a giant committee that spends weeks arguing about if it's something they should even decide on, etc."

This kind of premature generalisation by committee is what has pulled OpenStack down; a situation from which it is now apparently recovering. CNCF seeks to avoid this, by encouraging projects towards interop but not in mandated ways.

Cool.

Do you ask projects to support all the implementations or just choose one?

Projects can do what they like. We believe that users, communities, market pressures, and so on, will drive good outcomes here. For example to date, all projects have worked to interoperate of their own volition. No committees were formed to achieve this.
