A risk-averse city council wants limited blast radius on day one of a citizen portal redesign. Which deployment strategy best minimizes initial user exposure?
Select an answer to reveal the explanation.
Short Explanation
Limited blast radius means "few people see the new thing first." Canary is built for that — a small citizen slice, then grow if metrics look good. Flipping everyone at once (blue-green 100% cutover or big-bang) is the opposite of a tiny day-one risk appetite.
Full Explanation
Canary deployments intentionally constrain initial exposure so defects affect a small cohort before wider enablement. Full-environment blue-green switches and fleet-wide in-place upgrades enlarge blast radius on day one. Progressive percentage-based exposure aligns with a risk-averse rollout policy better than immediate 100% cutovers.
