Future Release Infrastructure

Registered by Kate Stewart

As we move towards new markets and challenges to satisfy those markets, its time to re-examine how we've been doing things, and start planning for the longer term infrastructure goals we want to have in place for the next LTS and beyond. The build infrastructure has evolved since it was started 8 years ago, and several things work very well, while others could benefit from some brainstorming about what we'd do if we had a clean slate.

This is a discussion session to start the brainstorming about a roadmap to evolve our release infrastructure to be better able to support: servers, embedded devices, 100x users.

Questions for the discussion:
   What are the release requirements these new markets are going to need to enable us to participate in them?
   If we had a clean slate to start from, what would an ideal archive, build infrastructure, tools, methodology look like?
   Do our current milestones and freeze windows, fit new requirements?
   Do we have redundancy and flexibility to be able to adapt and react?
   How do we remove the manual bits of release process and make it more robust?
