Dailymotion started with two-week release cycles, but getting test feedback was slow and involved many manual steps. They moved to Kubernetes and Jenkins X, which allowed developers to test their changes immediately, using preview environments.
Now they automatically release each successful pull request, for an average of 10-15 times a day. Configuration is managed in Git as well and updated the same way as the rest of the code. This is how most organisations do it now and he specifically cites this as a benefit.
Vincent Behar also discusses some of the challenges that come with their new approach, like how to roll out changes without affecting all customers in case they turn out to be bad.
