This may be true for AWS but (in my experience since 2014) it is not true for Google compute engine. On GCE, VM instances automatically migrate when the host is rebooted, and VM availability and uptime is impressive. Also, on GCE, the default recommended disks are all persistent, since they are block devices mounted over the network; this wasn't the case years ago, but is now, and it is very impressive.

- zeroxfe 10y agoYep. GCE VM migration and persistent storage is really amazing, and getting better with every release, however there are still limitations and caveats that can get you in trouble (especially if you have very tight latency requirements.) Glad you like it! Good luck with your startup. Disclaimer: I work on infrastructure systems at Google :-)
