dev.infra-canary-pct Calculator
Calculates canary deployment traffic percentage and the sample size needed to detect a given regression with statistical significance in a cloud infrastructure and DevOps context. A 1% canary needs approximately 1,000+ requests to the new version to detect a 50% error rate increase with 95% confidence — smaller canary percentages require longer exposure windows.
Inputs
Users
Reference formula or conversion factor shown for context.
Pct
Reference formula or conversion factor shown for context.
Error
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
canary users
Sample size or count used in the calculation.
expected errors
The difference between the computed result and the exact or true value — a measure of approximation accuracy.
blast radius
The computed radius -- half the diameter.
grade
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
safe threshold
Reference formula or conversion factor shown for context.
