First, thanks to Andrew for starting this thread. I think it's an important discussion.
Second, the problem with the analogies made so far is, IMHO, at the API level and what it does to the ecosystem. Let's take, for example, Apache HTTP Client stuff. 3.1 and 4.x are wildly different object models. But that's OK for the Apache model in a way that isn't for OpenStack. When I decided to move Dasein Cloud to the new stuff, it was on my time frame, not Apache's. With OpenStack, the deprecation of APIs is hugely problematic because the ecosystem is "live dependent" on the APIs. If I roll out a new version into a infrastructure with rich tool support and that version has API inconsistencies, I immediately and irrevocably break critical operational tools. With the Apache stuff, there's no external visibility into the HTTPclient APIs. It's just my code that I can compile and test pre-deployment. It's a problem for any tool with a public facing RESTful API. That's why I believe in never deprecating except in extreme circumstances. The most successful cloud API out there, the EC2 API, never breaks existing tools. NEVER. Seriously, never. -George On Aug 10, 2012, at 9:33 PM, Frans Thamura <fr...@meruvian.org> wrote: > Openstack is like linux kernel for cloud > > Anyone welcome to.create distro on it like ubuntu tolinux... and yea ubunti > cloud to openstack > > On Aug 11, 2012 8:46 AM, "Eric Windisch" <e...@cloudscaling.com> wrote: > > > On Aug 10, 2012, at 20:49, Nathanael Burton <nathanael.i.bur...@gmail.com> > wrote: > >> I personally equate OpenStack to the Linux Kernel.
