Answer: Utilize a Canary deployment method for the new version.
The Canary deployment method is ideal for this scenario because it allows for a partial rollout of the new version to a select group of users. This enables performance evaluation against the baseline deployment with minimal user impact in case of failure. Options A, B, and C are less suitable: Blue/Green and Red/Black deployments switch all traffic to the new version at once, affecting all users if a failure occurs, while Rolling updates gradually replace instances, increasing the number of affected users as the deployment progresses.
