Canary deployment serves a new version to a limited share of live traffic; shadow deployment mirrors requests to a candidate while users continue receiving the current system’s response.
Dengarkan panduan iniDiceritakan oleh AI · ~1 min
A canary exposes a candidate to a controlled portion of real traffic and can measure effects on users. A shadow deployment sends copies of production inputs to a candidate for comparison but normally keeps the current model’s response in the live path. Shadowing can avoid exposing users to candidate outputs, yet consumes compute and may copy sensitive data. Neither deployment method alone proves causal improvement; define metrics, traffic assignment, and stop conditions.
Route a small, predeclared traffic segment to a canary and compare guardrails.
Mirror requests to a shadow model while discarding its response from user delivery.
Check privacy, load, and data-handling implications before mirroring.
Define rollback and promotion criteria before rollout.
Progressive delivery can combine shadow evaluation with a canary, but policies and statistical thresholds must be designed for the application. Avoid universal rollout percentages or durations.

Canary deployment serves a new version to a limited share of live traffic; shadow deployment mirrors requests to a candidate while users continue receiving the current system’s response.
Canary memaparkan sebagian kecil pengguna sebenarnya ke versi baru sehingga masalah dapat diatasi dengan radius ledakan terbatas sebelum peluncuran penuh.
Model bayangan memproses salinan permintaan sebenarnya, namun keluarannya tidak pernah sampai ke pengguna — mereka malah dicatat dan dibandingkan.
Shadow responses are discarded, but duplicate inference, data handling, or unintended side effects still need controls.
A canary serves the candidate to a defined segment; a shadow compares without serving its candidate response.
The guide recommends defining routing rules, metric thresholds, sample duration, and rollback ownership before rollout.
