Everyone who says this is a bad price for the hardware, please link me to any other bare metal server for rent at 16e/mo. I haven't seen it, not at Hetzner, nor anywhere else. You can hate on it all you want, but this is simply a unique offering.

For what application is bare metal server rental particularly useful? (as opposed to either own colo or low end VPS)

Compared to VPS, you give up some flexibility (bare metal servers are generally only available for a month), but, at equivalent price, the specs are better on bare metal servers.

Colo can be even cheaper, but it needs additional skills, and more upfront money investment. It's a whole different world.

I think by "interesting" you meant to write "terrible". I'm wondering who on earth is the market for this? 32 bit ARM (even A15) is not a great server platform. If it had been 64 bit ARM with a real amount of RAM and an SSD then it might be more interesting. Even there (and I say this as someone who has an APM Mustang under my desk), it's more likely of benefit to people hosting web servers at scale than for VPS.

> I'm wondering who on earth is the market for this? People whose web pages generate a lot of traffic (10TB allowed) with low CPU usage, i.e. static pages and similar.

Wouldn't those users be better served by a $5 VPS? They're cheaper per-month, have no setup fee, and probably even get provisioned quicker.

What exactly is stopping ARM boards to have high IO? Just allow people to use a normal 2.5" SSD or even m2 and you have a really nice machine! For example, the latest Raspberry Pi 2 has a quad-core CPU which is faster than my 1st machine (and maybe even my 2nd and 3rd) but is severly handicaped by the IO speed which is limited to USB (plus, all the USB ports and Ethernet using the same controller for extra slowness).…

It really is just a question of SoC choice: the iMX53 (for example) has SATA, but in single quantities just the chip costs the same as a whole Pi.

the iMX6 adds PCIe 2.0.

It's not, though.

online.net will sell you an x64 server for as low as 6e/m, and with scaleway you can get an ARM server with a significantly better storage story for 10e/m.

There are a myriad of low-cost dedicated server providers in this price range that are not selling SD cards and other consumer hardware.

As linked elsewhere in this thread, its plenty achievable to have bare metal at 16e/mo or less even, between Online.net and Kimsufi.

Alright, thanks that's exactly what I wanted to know. Why don't the U.S. have good dedicated server offerings? Hetzner, Online, Kimsufi, they're all in Europe for some reason. Across the pond I've only found really expensive managed hosting solutions and VPS.

Kimsufi is available in Canada.

SoCs with 8GB onboard is a pretty niche chip, but other than that it's all out there. The Raspberry Pi/2 is actually a pretty poor offering - you can do better, even at the same price, The Pi Foundation just does a better job of marketing.

Specific models are the ODroid XU4, the CubieBoard or Cubietruck, the Banana Pi, etc.

They're not cheap, but the Jetson TK1 is an extremely powerful offering for this category based on the Tegra K1 SoC. You get SATA, USB 3.0, mPCIE, 1GigE, GPU with 192 Kepler cores, etc. If you need some grunt you can even do CUDA compute. Again, I'm still waiting for my Tegra-X1 based Jetson, NVIDIA :<

Well, its nice that ARM servers are coming available, even if they don't seem quite that desirable as they are. Could be nice for ARM build CI server. I wonder how the performance compares to say the scaleway[0] offerings, I would guess the SD card storage doesn't compare favourably.

Anything with SD card storage will perform very poorly. Anything that uses USB 2.0 as a system bus will perform like dogshit.

Using real SSDs on a real SATA channel makes an immense difference, not just in performance but also in system stability. SD cards are meant to be linearly loaded up with files, dumped to disk, then erased. They do not handle highly random write loads with sectors of extreme write intensity very well, their wear levelling is very minimal and sooner or later you will burn them out if you're not careful. The typical way around this is using a write-protected SD card for bootstrapping (if necessary). You load a minimal driver stub, and then you either boot from a USB stick or you do a PXE boot from an image on the network.

USB 2.0 is way too limited to handle your entire system disk+network traffic+data disk load. You want USB 3.0 at a minimum if your computer is set up like that.

If you just want something real minimal maybe the SD card options are OK, but I highly, highly recommend a SSD-based system if you can swing it at all. If you're not going to see a ton of traffic, maybe you could build it out once and run it on your corporate network? That could be more appealing than a hosted or colo'd solution, depending on the task.

SD card is fine if you load your junk into memory and run out of ram. Few seconds of boot, but totally doable. Just need to go off box for mostly everything from logs to whatnot...

I will try to test if those "servers" would be good for task processing. Example: let's say I have a ton of websites to crawl (high IO, not much CPU, ideally parallel). I could use a couple of these to cheaply do the job. I am guessing that any job that is not CPU or memory hungry would fit the bill. Like crawling, sending a massive amount of emails, simple text processing, maybe even as a RabbitMQ server.

Would it beat a pair of $5 VMs from digital ocean though?
