I believe the instance goes away. If you've persisted data to EBS, you can attach the volume to a different instance. Anything outside of EBS is lost. However, if you created an AMI (AWS Machine Image), you can launch a new instance from that. (but it's a snapshot, not a live image, so it'll be only as up to date as it was when saved)

The instance isn’t terminated (gone). It’s either shutdown or rebooted depending on the type of hardware failure.
It doesn't get transferred to a different physical instance, right?

I have never seen it migrated to a different instance type, but it would be running on a different physical server.

Why would anyone even care
I think many would make assumptions about the state of the instance and their application, which are likely to be wrong.
Some virtualization platforms support live migrations (hyper-v and ESXi), but this isn’t something AWS supports (afaik). Anytime your instance is stopped/started or rebooted then you may end up on a different physical host.
