this is A, Canary is a Testing strategy not a deployment strategy.
B. Canary deployment: In this strategy, the new version of the application (the "canary") is rolled out to a small subset of users before it is made available to the entire user base. This allows you to monitor the performance and stability of the new version in the real-world production environment with actual traffic, but only affects a small group of users. If issues arise, the canary deployment can be rolled back with minimal impact.
