What does progressive delivery mean in a GitHub Actions deployment context?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Progressive delivery is gradual rollout with feedback loops—canaries and rings—not nuking environments, matrix sequencing trivia, or dropping branch protections.

Full Explanation
Progressive delivery reduces blast radius by exposing a new version to a subset of users or stages first, monitoring metrics/errors, then continuing or rolling back. In GitHub Actions this often maps to multiple environments (canary, staging, prod), optional manual approvals, wait timers, and separate deploy jobs gated on success. It is not about removing environments for speed, nor is it defined as matrix OS ordering. Disabling branch protections increases risk and is not progressive delivery. Implement health checks between stages, keep concurrency groups per environment, and automate rollback jobs when canary metrics fail.
