A few weeks ago I needed to change the volume type on an EC2 instance to gp3. Following the instructions, the change happened while the instance was running. I didn't need to reboot or stop the instance, it just changed the type. While the instance was running.

I didn't understand how they were able to do this, I had thought volume types mapped to hardware clusters of some kind. And since I didn't understand, I wasn't able to distinguish it from magic.

Changing the volume type on AWS is somewhat magical. Seeing it happens on-line was amazing.

Dunno about AWS, but GCP uses live migration, and will migrate your VM across physical machines as necessary. The disk volumes are all connected over the network, nothing really depends on the actual physical machine your VM is ran on.

Worth pointing out that the article is measuring provisioning latency and success rates (how quickly can you get a GPU box running and whether or not you get an error back from the API when you try), and not "reliability" as most readers would understand it (how likely they are to do what you want them to do without failure).

Definitely seems like interesting info, though.
