Just gonna point this out since I noticed it a few weeks ago and notice is still there, Hetzner has paused selling new colocation service: https://www.hetzner.com/colocation/ So this is probably a joke site or a scam.

Perhaps they just want to steal the parts out of the laptops. If they swindled 5K rubes out of their machines, that's a lot of resale money, no?

You really don't know how much it costs, do you? Check https://tinypilotkvm.com/collections/all-products these are the cheapest ones.

MSRP for remote-capable KVMs is irrelevant.

You (the person paying to co-locate hardware) don't buy the KVM that the colo facility uses. The colo facility hooks up the KVM that they own to your hardware and configures it so that you can access it. Once you stop paying to colo your hardware, you take your hardware back (or maybe pay them to dispose of it, I guess) and they keep the KVM, because it's theirs.

Yeah. I got bored a couple of hours after I posted that speculation and found several other colo facilities that mentioned that they'd do remote KVM. I'd figured that it was a common thing (a fair chunk of hardware you might want to colo either doesn't have IPMI or doesn't have IPMI that's worth a damn), but wasn't sure.

I think a raspberry pi setup would be the cheapest? Not as professional perhaps.

Yeah but for $6/mo you can get a tiny linode or digital ocean droplet, and not worry about hardware failing. It's true that a laptop probably has more resources than the smallest VMs, but no remote management interface and can't scale if you suddenly had a surge of traffic.

k8s doesn't really weigh you down, especially if tuned for the low end use case (k1s). It encourages some dumb decisions that do, such as using Prometheus stack with default settings, but by itself it just eats a lot of ram.

Now using CPU limits in k8s with cgroups v1 does hurt performance. But doing that would hurt performance without k8s too.

> I rent physical servers from them that have been previously rented to other customers. At some point hard drives fail. The comparison in this case is to Hetzner's VPS offerings, which are probably less powerful than the average "old laptop" but have a significant advantage in terms of hardware reliability. It's still possible for the host running the VPS to have problems which result in a crash or the VM equivalent…

I've run a 7 figure business from an SSD shoved in a sata2 DVD-ROM slot in a DC because the end customer was being obtuse about upgrading from their "high end, best practice" raid 10 discs.

You use so many big words for nothing. All you need are backups. When it dies you restore. Nobody will care.

Old laptops as low cost servers? Absolutely, build a homelab in your own basement, rent a cheap VPS, set up wireguard and viola - instant data center for tens of dollars per month. It's not production grade but you'll learn a ton. But colocation? Strip away the learning component and add production uptime requirements - why would you even consider using crusty old laptops for this? If you have production grade needs,…

I have always dreamed of substituting a really expensive rack of servers with a couple of elderly laptops, with their built in UPS, handy screens, keyboards and trackpads. However, for pet projects, I now have a better way of being cheapskate. Some ecommerce software stacks really need gargantuan amounts of RAM and CPU, which gets expensive on the cloud. However, it is possible with some software to have everything m…

> it is possible with some software to have everything massively cached, with the cloud doing that, with the origin server in my basement, only accessible from the allowed cache arrangement

Do you mean a setup like:

    client -> cloud(HAProxy+Varnish) -WireGuard-> basement(backend)
Or something else?
