Another cool thing I've experienced with Google Cloud: a while ago I had a VM running, with the default 7.5 GB RAM for a 2 CPU VM. Then when I came back some days later, I got a message saying that the VM had only been using ~3GB of RAM, and that I could save money by reducing the VM's RAM, by clicking "this button". Then I clicked the button, the VM's RAM was reduced and, if I recall correctly, it didn't even require a reboot.

That's not only technically impressive, it's also really good customer service.

You can't resize running VMs — Google is good, but not that good. You can stop, resize, and start again, which is still better than AWS (unless they support changing the instance type now). I suspect that the button you talk about did that.
