問題文
A platform team is documenting a capability that rolls a new version out to a subset of users first. Which relationship to continuous delivery does the documented definition of progressive delivery state, and which techniques does it name?
選択肢
- It builds on continuous delivery by rolling out gradually to a subset of users, using techniques such as feature flags, canary releases and split testing.
- It is a form of continuous integration applied to production traffic.
- It is a prerequisite for continuous delivery, since users have to be segmented first, so a team would set up the segmentation before it could deliver continuously at all.
- It replaces continuous delivery with a model in which the automated path to production is reserved for a subset of users and the remaining users receive changes through a separate release process that the platform team controls.
