You aren't really paying for computing power and storage - you are paying for power/network/facility/server redundancy and availability.
We host out own servers, and the bulk of the time is ensuring that the power doesn't go out, that there is a backup internet connection, that the HDs are on RAID, that the server has a backup server available (and the router, and the switch, and the NICs), and that the management network is available, and that the location has proper security monitoring, and that the offsite backup happens nightly, and that we have an employee that knows how to do all of the above... All of that is time consuming and expensive.
...BUT, some people/some companies actually enjoy that sort of thing, in which case, it can work out financially - though often you're sacrificing one of the 9's in your 99.99% uptime/reliability.
- horsawlarway 5y agoIn almost all cases - you won't actually get 99.99% uptime from your cloud provider anyways. That's around an hour of downtime every year. A much more reasonable estimate is 99.9% - or approx 9 hours, unless you're doing serious planning and spending to account for outages. Hell - the Dec 7th 2021 outage for AWS was nearly 10 hours alone. On your own, 99% is probably a reasonable prediction (roughly 3.5 days), and I think people vastly over-estimate how much small amounts of downtime actually matter for lots of services.
