You are designing a deployment technique for your new applications on Google Cloud. As part of your deployment planning, you want to use live traffic to gather performance metrics for both new and existing applications. You need to test against the full production load prior to launch. What should you do?

Not sure if using live traffic is the best idea... what if it breaks?

A/B testing with traffic mirroring sounds interesting, but does it really work?

Rolling updates can be tricky under full load.

Blue/green deployment is safer, though.

Canary deployment is great for testing with live traffic!

A/B testing with traffic mirroring sounds familiar, and I think it might be the best option for gathering metrics while still using live traffic.

I practiced a similar question about rolling updates, but I don't recall if they are ideal for testing with live traffic.

Blue/green deployment seems like it could work, but I think it might not utilize live traffic as effectively as needed for performance metrics.

I remember studying canary deployments, but I'm not sure if they allow for full production load testing like this question suggests.

This is a tricky one. I'm torn between a few of the options, but I think the best approach here would be to use A/B testing with traffic mirroring. That way, we can gather performance data on the new version without disrupting the existing production traffic. I'll make sure to explain my reasoning in detail.

Okay, I've got this. The key here is that we need to test the new application against the full production load before launch. That means we'll want to use a deployment strategy that allows us to gradually shift traffic over to the new version. I'm pretty confident that the right answer is option B, blue/green deployment.

Hmm, I'm a bit unsure about this one. I know there are different deployment techniques, but I'm not totally clear on the differences between them. I'll have to think this through carefully.

This seems like a straightforward question about deployment strategies. I think I know the answer, but I'll double-check the details just to be sure.

This is a tough one, but I think the answer is D. It's like doing a trial run of your new app before the big game. You don't want any fumbles on launch day, so traffic mirroring is the way to go.

I agree with Ligia, A/B testing with traffic mirroring is the way to go. It's like a dress rehearsal for your new app - you get to see how it performs on the big stage without any embarrassing flubs.

Rolling updates would be a bit risky in this scenario. You want to test the full production load, so a more controlled approach like traffic mirroring is probably better.

Blue/green deployment could also work, but it might be overkill for this use case. I think A/B testing with traffic mirroring would be a more efficient approach.

I agree with Corinne, canary deployment allows us to gather performance metrics before full launch.

Canary deployment seems like the right choice here. It allows you to test the new application with a small subset of users before rolling it out to the full production load.
