> dismiss the virtue signaling of high resilient ... So you're saying it's impossible to improve reliability from 97% to 99% because you can never make it to 1

  If your single-AZ, single-region cloud is not giving you 3 or 4 9's of reliability out of the box, you are using the wrong cloud. Multi-AZ and multi-region add complexity and cost much more quickly than they add reliability. Sometimes it is worth it. Sometimes it is not.

    Depends on your needs, but having your data & database multi-az to ensure durability can avoid you having to restart from backups. I'm thinking about an old AWS incident were they actually lost EBS data: https://www.bleepingcomputer.com/news/technology/amazon-aws-outage-shows-data-in-the-cloud-is-not-always-safe/ https://www.bleepingcomputer.com/news/technology/amazon-aws-... Also make sure your backups are in a different AZ (thinking about OVH ...) or region or even at a different provider.
