Explanation:
The correct approach is to deploy the new version using the no-promote flag to prevent it from receiving all traffic immediately. After deployment and testing, traffic can be split using cookies to ensure a consistent user experience. This method is more precise than IP-based splitting. Options A and B are incorrect because deploying without the no-promote flag would direct all traffic to the new version. Option C is incorrect because random distribution does not guarantee a consistent user experience.
Your team is planning to introduce new functionality gradually to monitor for errors, which includes significant changes to the user interface. You've decided on a canary deployment using traffic splitting, starting with 15% of your users. How should you configure traffic splitting to ensure users have a consistent experience?
A
Deploy the new version and split traffic based on IP or cookie distribution.
B
Utilize the gcloud app deploy command with the distribution flag for simultaneous deployment and traffic splitting.
C
Deploy the new version with the no-promote flag and split traffic randomly.
D
Deploy the new version with the no-promote flag and split traffic using cookies.
