Google Professional Cloud Developer Question 301
Select 3Google Cloud PlatformYou are deploying a new feature for a global e-commerce application hosted on Google Cloud. The feature is expected to significantly impact the user experience, and you want to minimize risk while monitoring user feedback. Which rollout strategies should you consider for this deployment?
- A
Blue/Green Deployment
- B
Canary Deployment
- C
Big Bang Deployment
- D
Feature Flags
- E
Recreating all instances at once
Show answer and explanation
Correct answers: A, B, D
Explanation
Blue/Green Deployment, Canary Deployment, and Feature Flags are all appropriate rollout strategies for minimizing risk and monitoring feedback during feature deployment. These strategies allow for gradual or controlled rollouts, enabling you to verify the feature's impact and make adjustments if necessary. Big Bang Deployment and recreating all instances at once, however, are high-risk approaches that lack the flexibility needed for critical feature rollouts.
- A. Correct.
Blue/Green Deployment is a good strategy for minimizing risk because it allows you to test the new version on a separate environment and switch traffic to it only after verifying its stability.
- B. Correct.
Canary Deployment is suitable for gradually rolling out the feature to a small subset of users, which allows for monitoring and feedback before scaling up to the entire user base.
- C. Incorrect.
Big Bang Deployment involves deploying the feature to all users at once, which increases risk and does not allow for gradual monitoring or rollback. This is not recommended for critical feature rollouts.
- D. Correct.
Feature Flags allow you to roll out the feature to specific users or regions dynamically without redeploying the application, making it a flexible and low-risk option.
- E. Incorrect.
Recreating all instances at once is a high-risk approach that does not allow for gradual rollout or rollback. It is not considered an appropriate rollout strategy.
