**Type:** multiple_choice
**Topics:** topic_1

## Question

The new version of your containerized application has been tested and is ready to be deployed to production on Google Kubernetes Engine (GKE). You could not fully load-test the new version in your pre-production environment, and you need to ensure that the application does not have performance problems after deployment. Your deployment must be automated. What should you do?

## Correct Answer

_See scenario._

## Explanation

Selected Answer: A
I vote for A as in Blue/Green deployment you can rollback quickly after facing the performance issue, but in Canary you can detect performance issue on partial deployment and rollback before the issue get affected.
