Exam Professional Cloud Developer topic 1 question 84 discussion

Let's look at why the other options are less suitable: B. Canary Deployment: This strategy gradually rolls out the new version to a small subset of users while the majority of traffic continues to use the old version. This is useful for testing and monitoring the new version before full rollout, but it doesn't immediately route all traffic to the new version. C. Rolling Deployment: This strategy gradually replaces instances of the old version with instances of the new version. While it allows for a gradual rollout, it doesn't guarantee that all traffic is immediately routed to the new version. D. Recreate Deployment: This strategy involves completely replacing the old deployment with the new one. This is a simple approach, but it doesn't provide a way to easily revert to the previous version if there are issues.

no... qn 9 is canary. because it wants to minimize the impact, you runs two versions together for testing. This one wants all traffic use the new version. so, it can be A or C. A is recommended and clear cut; BUT costly. C is cheaper; but, it does not routed all to new version IMMEDATELY. so. I pick A, since, question did not mention cost.
