“Create a canary deployment pipeline: a release candidate passes pre-release tests, deploys to 5% of traffic, and is monitored for errors, latency, and conversion. If guardrails fail, remove the canary, restore the prior version, and review the issue. If they pass, expand to 25%, monitor again, then either hold and investigate or deploy to all traffic and complete the rollout.”
看懂背後的決策。
Limit the first deployment to a small traffic share.
Define which error, latency, and conversion changes are acceptable.
Increase traffic only after the first observation period passes.
Remove a failing canary and restore the prior version.
Use this for releases that can be routed to a controlled share of production traffic.
常見問題
What is a canary deployment?
It is a release approach that sends a new version to a limited share of production traffic before making it available to everyone.
What are deployment guardrails?
They are measurable limits, such as error rate or latency, that determine whether the rollout can continue.
Why monitor after expansion?
A version can behave differently under more traffic, so a second observation period checks the release before full rollout.
