I know that co-location means “customer owned hardware”, but in this case, I think I’d way rather rent data center owned RPis and just pay them money rather than sending in hardware, having to cycle out hardware if/when it fails, etc. It also means the colo is running whatever random power supply I send them, which seems like something they’d want to avoid and means that there’s all the inefficiency of 12 supplies pe…

I like the idea in theory, but I can’t entirely agree with the “Green” designation. Putting 12 Raspberry Pis, 12 USB SSDs, 12 switch ports, and cabling and power supplies for all of the above adds up quickly. From a pure compute-per-watt perspective using typical cloud workloads, I’d still expect a run of the mill shared cloud server to be more efficient. It would also allow for more burst overhead for individual wor…

> This is an interesting option for people who need a specific Raspberry Pi hosted somewhere. What is that use case though? The page says that they only host regular Pis and optionally a USB SSD. So they can't do anything that a regular cloud server can't do - no custom hats, etc. I have a Pi 4 home server, and the biggest issue right now is that my home upload is a bit weak for remote video streaming. So this produc…

Edit: This is in response to the "fleet of Pi's" question, obviously a Mac Mini is not going to be cheaper to rent than a single Pi! The aforementioned VPS route is the better way to go for that case.

Scaleway will give you an 8 core 16GB RAM 256GB SSD M1 Mac Mini for €0.1/h. It may not sound like much of an increase from core count but it is ~10x faster for multicore which means it probably comes out on top for perf/€, perf/Watt, and total perf compared to a rack of Pi 4's for any such distributed ARM use case.

For pure traditional cloud a Graviton2 instance on AWS is probably more green, albeit probably less cost efficient to the user.

Earlier quoted context omitted.

It seems like either feeding 5v via custom power supply on GPIO or requiring PoE HATs (though those are slightly less efficient...) would be a better scalable option. One massive thing that seems to be missing here (unless I've missed it) is any kind of remote ability to manage the server, eg at a minimum remote power cycling, if the Pi locks up. It would also be nice to get remote console but that would require even…

Agree, a central supply with a 3A MOSFET for control and a PTC for basic protection would give a lot more functionality and reduce customer downtime and smart-hands touches.

At that point what you're describing has little resemblance to a hosted RPI though, the complexity justifies just making something custom that's better suited to the task than shoe horning Raspberry Pi hardware into a rack.

That’s €72/mo. Different price class there.

This is neat but from a scaling perspective it doesn’t make sense. A single server grade Xeon chip can expose the same compute power as a cluster of these devices, with better performance across the board (memory access, peripherals, etc)

Just trying to grok a legit use case?

Nervous people about spectre? Only thing I can think of besides renting a VM.
