Reveal correct answer
Correct answer: B
Explanation
Canary deployment is the recommended strategy for minimizing the impact and the number of users affected by issues that arise after deploying a new version of an application. According to the Professional Google Cloud Developer documentation, this strategy involves deploying the new version to a small subset of users, monitoring its behavior, and gradually increasing the traffic to it if everything looks good. This approach allows developers to detect and fix issues early on, without affecting the majority of users. In contrast, blue/green deployment involves switching all traffic to the new version at once, which increases the risk of downtime and affects all users simultaneously. Therefore, the correct option for reducing the impact and the number of users affected is the canary deployment strategy.Discussion
