You have to deal with a lot more stuff. You have to order/pay for a server (capex), mount it somewhere, wire up lights-out-mgmt and recovery and do a few more tasks that the provider has already done.

Then, say if the motherboard gives up, you have to do quite a bit of work to get it replaced, you might be down for hours or maybe days.

For a single server I don't think it makes sense. For 8 servers, maybe. Depends on the opportunity cost.

We need more competition across the board. These savings are insane and DO should be sweating, right?

The comparison is somewhat skewed, since they went from an (expensive) virtual server to a cheaper dedicated server (hardware).

One of the new risks is if anything critical happens with the hardware, network, switch etc. then everything is down, until someone at Hetzner go fixes it.

With a virtual server it’ll just get started on a different server straight away. Usually hypervisors also has 2 or more network connections etc.

And hopefully they also got some backup setup.

It’s still a huge amount of of savings and I’d probably do the same of I were in their shoes, but there is tradeoffs when going from virtual- to dedicated hardware.

“Your own server in a colo” means going to the colo to swap RAM or an SSD when something goes wrong. You rent a server and the benefit is the rentor has spare parts on hand and staff to swap parts out.

What are you doing for DB backups? Do you have a replica/standby? Or is it just hourly or something like that? Because with a single-server setup like this, I'd imagine that hardware (e.g. SSD) failure brings down your app, and in the case of SSD failure, you then have hours or days downtime while you set everything up again.

Hetzner normally advertises their hardware servers as 2x 1 TB SSD, because it's strongly recommended to run them in SWraid1 for net 1TB. (Their image installer will default to that)

Once the first SSD fails after some years, and your monitoring catches that, you can either migrate to a new box, find another intermediate solution/replica, or let them hotswap it while the other drive takes on.

Of course though, going to physical servers loses redundency of the cloud, but that's something you need to price in when looking at the savings and deciding your risk model.

And yes, running this without also at least daily snapshotting/backup to remote storage is insane - that applies to cloud aswell, albeit easier to setup there.

I always appreciate savings posts, but is $14k USD annual really make or break for a Turkish business? I would not know.

That's not the point. You should be asking why DO is so much more expensive. Not everyone likes wasting money.

Guess I've been enjoying it for so long, I feel so stupid. Thanks for this.

Yeah. This blog post reads like it was written by someone who didn't think things through and just focused on hyper-agressive cost-cutting.

I bet their DigitalOcean vm did live migrations and supported snapshots.

You can get that at Hetzner but only in their cloud product.

You absolutely will not get that in Hetzner bare-metal. If your HD or other component dies, it dies. Hetzner will replace the HD, but its up to you to restore from scratch. Hetzner are very clear about this in multiple places.
