Open Stack

Thanks Rob - so when capabilities become accepted in the market Defcore ensures support for them moving forward, until it's no longer appropriate.

I'll take up my branding concerns with the marketing side of the house.

Carol,

DefCore can't.  IMHO, it one of Vendors' roles to select, validate and support new capabilities.  DefCore comes along after those capabilities are broadly adopted.  It would be an anti-pattern if we selected capabilities that were only in one or two products/distros.

The reason to move away from releases was to decouple this exact discussion.  DefCore is not about features in releases but long term capabilities of the platform.

Rob - With my Branding hat on, it's less about API uptake and more about the connotation of the Brand on a release. If the OpenStack Brand on a distro means a promise of quality, interoperability and backward compatibility how can we deliver on that for new capabilities without having evaluated them and ensure there's appropriate testing?

Carol,

Let me turn that around.  If a project released new capabilities out of cycle, how quickly would you expect them to surface into the DefCore guidelines?

By design, we select for widely-used APIs.  So, how fast should we expect a new feature to get wide adoption.

I expect that the unpredictability of project releases will create challenges in many ways. Branding is one of them - if a project releases new capabilities out of cycle to the core-projects release of the Defcore definition update, those new features will not be covered by the Brand (which means they haven't been validated to a certain level nor is there any backward API compatibility promise). How will an end-user know that?  If the Brand doesn't simplify the purchasing process for the end-user, then we're not on the right track..imho.

Good questions.  We're including which releases are covered in each guideline so, for example, you can track DefCore 2015.07 to the I,J & K releases.  You can't use that guideline against H or L

Hi Carol,

I agree with the concern but I think (I didn't attend the F2F) some of this may be driven by the fact that we don't necessarily have a concrete definition of what a release may look like in the future.

If the releases (due to project structure reform) end up having a cadence with a usual group of components then I could see aligning with releases but I think some of that is TBD at this point, therefore this seems like a safe bet.

Thanks,
Shamail

Is the expectation that a vendor will pull the upstream  for the month/year Defcore test and ship a product?  If a vendor release cycle is offset by 2 months, what would use to validate their Brand compliance? My thought is by that time new things will be included in a variety of projects that will be included in the Vendor release but not comprehended in the 2 month old Defcore definition.
