Creating an Unmanaged Instance Group doesn't sound like it would help with cost savings, but I can't recall the specifics on why that is.

I remember something about preemptible VMs being cheaper, but I don't think they would work for a business-critical workload since they can be terminated.

I'm not entirely sure, but migrating to a Managed Instance Group seems like it might add unnecessary complexity for a fixed workload.

I think purchasing Committed Use Discounts could be the right choice since it locks in lower rates for a stable workload.

Ah, I remember learning about the role management features in SMC3.0. I'm pretty confident the answer is System Configuration, but I'll double-check the other options just to be sure.

The key seems to be designing the apps carefully, whether they are smaller or bigger. I'll focus on that in my answer.

Okay, I think I've got a good strategy here. I'll focus on keeping everything on the same dashboard and reusing the existing permissions and notifications.

Ugh, I hate questions about web standards and privacy features like this. It's just not my strongest area. I'll have to take my best guess here and hope for the best.
