Progressive Delivery

An evolution of continuous delivery that releases changes gradually with automated analysis, using canaries, feature flags, and traffic shaping.

Definition

Progressive delivery tools such as Argo Rollouts and Flagger shift traffic in steps and automatically promote or abort based on metric analysis. It minimizes blast radius while keeping delivery fast.

Example

Argo Rollouts shifts traffic 10/30/60/100% with Prometheus analysis between steps.

Exam tip

Look for 'automated metric analysis plus gradual exposure' to identify progressive delivery.
