Technical Committee Highlights March 21, 2016

Long time, no see!

Poppy and our Open Core discussion

The Poppy team applied to add the project under OpenStack governance. Poppy, for those of you not familiar with it, provides CDN as a service. It’s a provisioning service – like other projects in OpenStack, such as Nova – but for CDNs. The overall proposal seemed to be fine except for one thing, there are no open source solutions for CDNs. This means Poppy provisions CDNs based on other commercial services and it requires consumers of Poppy to have an account in one of those CDN services to be able to use it.This presents several issues from an OpenStack perspective. One of them is the one mentioned before, which is that using Poppy requires clouds to rely on other CDNs. Another issue is that there is not good way to test the service in OpenStacks gates as there’s no open source solution for it. The OpenStack infra team won’t be subscribing to any of those CDN services for testing Poppy and nor is the Poppy team either.

There were quite a few discussions on this topic and the TC voted on whether the open core “issue” was critical enough to allow or reject Poppy from the big tent. In the review, there are different points of views on whether Poppy is actually Open Core or not and whether it should be allowed into OpenStack’s big tent regardless of the lack of an open source CDN solution. Ultimately the TC decided to reject the Poppy proposal in a close vote, 7-6.

Mission statement, take 2

As Russell Bryant puts it well in this Foundation mailing list thread, the OpenStack mission statement has held up pretty well for the life of the project. Discussions started about updates to ensure we include some key themes as focus areas for our growing community: interoperability and end users needs. The OpenStack technical committee has created an iteration on the mission statement, and the board is discussing as well. Take a look at the revisions so that our modifications can get buy-in across the community.

New projects

The OpenStack big tent welcomes the following official project teams:

  • Dragonflow, a distributed control plane implementation of Neutron that implements advanced networking services driven by the OpenStack Networking API.
  • Kuryr, a bridge between container framework networking models and the OpenStack networking abstraction.
  • Tacker, a lifecycle management tool providing Network Function Virtualization (NFV) Orchestration services and libraries.
  • EC2API, provides an EC2-compatible API for accessing OpenStack features.

New tag: stable:follows-policy

This new tag allows for indicating which deliverables follow the stable policy. The existing `release:has-stable-branches` tag that had been used so far ended up only describing if a deliverable has a branch called “stable/something”, and therefore did not properly indicate that stable policies are being followed. The new tag aims to cover that area and should eventually completely supersede the existing tag. You can read more about this tag in the tag reference page.
