Continuous deployment - the production version of the well known continual integration process - is very appealing to large deployers: it reduces the time to roll out security patches and reduces the risk of each production push.
However, CD isn't something that can be bolted on - like CI it requires the upstream code change process to support it (for instance, with CI the test suite has to be fast enough to run per-commit).
With CD trunk has to be always deployable, be able to run stably with skewed service versions and for DB migrations to be extremely fast.
In this session I want to get the ball rolling on us stepping up to CD from our current CI system, for at least all the core projects.
I expect this to involve assessing how much interest there is from contributors, as well as technical discussion on the logistics and overheads of delivering a CD ready trunk.
