> local servers tend to be much faster and cheaper than cloud.

Of course, running a server in your house is not going to achieve five or even three 9's of reliability, and even colocating a single rack in a single location might be more expensive than putting that infra in AWS (depending on how data-heavy your use case is, given AWS' exorbitant data transfer costs).

you can hit three nines even if you're down for 1.5 minutes every day, or ten minutes a week. It's really not as hard to hit as it sounds. For a compute heavy process that isn't end user facing (e.g. batch processing) it's perfectly viable.

Also, most cloud providers don't guarantee five nines anyway. GCE SLA is 99.5 on a single instance, 99.99 on a region
