Ops confuses a canary (small user percentage) with blue-green (full parallel environment switch). What is the key distinction?
Select an answer to reveal the explanation.
Short Explanation
Canary is a teaspoon of the new soup for a few diners; blue-green is two full kitchens with a door swap. Subset exposure versus whole-environment cutover is the distinction. They are related release tactics, not the same thing with different logos.
Full Explanation
Canary deployment constrains risk by serving a small traffic or user subset on the new version while most traffic remains on the stable build. Blue-green maintains two full environments and redirects traffic for cutover and rollback. Conflating them leads to wrong capacity planning and wrong rollback expectations; they are not mere naming variants.
