Terms beginning with P cover much of the machinery that moves code from a commit to production - pipelines, promotion, provisioning and the patterns around them. Each definition below is written in plain English and kept short enough to quote.
A pipeline is an automated, ordered sequence of steps that builds, tests and ships your code every time it changes. Each step runs only if the previous one succeeds, so a single commit can flow from source control to a live environment without manual handoffs.
