Remotely reboot or making backups I agree wouldn't make for abuse. I was talking about instant activation.
https://aliendata.com is my VPS company. we provide shared and dedicated cores starting at $1.50.
I agree that it does need an interface to better work with them.
Takes time to design a system that will work.
We will do whatever we have to to make things work for you though.
I suspect half of a Broadwell core, i.e., one hyperthread, has similar compute speed (assuming the other hyperthread is also in use) as a single ARM core on the 4B. For this reason and the fact that you only get 1GB of RAM, the VPS you mention has about 1/4 the capacity of a Pi 4B and appears to be priced accordingly.

My only point of concern is the 10GB storage of the VPS is likely more reliable than an SD card and easier to provision. Both these difficulties could be remedied (likely with an overall cost savings) by switching to network boot and devising a way to remotely reset the Pi so that it reboots into whatever image is currently ready for it on the file server.

I agree with the network booting.
I am testing that out to see how well it goes.

I've been thinking about general viability of providing single-tenant Pi 4B servers as you are doing and understood
  • Typical 2U colocation is at least US $60 per month.
  • It is possible to squeeze 24 Pi's, a switch, power supply and a couple large capacity HDs in 2U.
Then, assuming 50 percent occupancy one needs to charge

60/12=5 US dollars per month

just to cover the colocation rent.

I suspect the low power requirements of the Pi and your relationship with the data center have allowed you to make use of excess space without consuming appreciable AC and power resources. Whatever the reason, that makes the rate of 5 per month seem very good from the customer point of view.

Are there future plans or a roadmap for guiding people how long and how many Pi's will be available at this price?

Actually if you check out the site https://aliendata.com. My rackspace is only $10 per U.
Now plus the mix of a POE switch to power the RPIs and bandwidth. The costs go up.
Hmm 24 RPIs. using what kind of racking were you looking at? I would like to know.

I measured a longish 2U server chassis and decided there was space to fit two rows of 12 Pi 4B computers standing on edge along with a suitable power supply, a desktop 24 port switch and some hard disks. I had thought about squeezing in an ITX server board for a file server, but decided the space would get crowded and two of the the Pi computers could do the job instead. Thus, only 22 Pi's would be available for the tenants. It would require a bit of custom mounting to secure everything, but likely not that difficult.

The design and pricing was mostly to get a back of the envelope estimate on the feasibility of the business model and compare prices rather than actually build a cloud or something.

The price of $10 per U per month seems very good and makes the Pi cloud much more practical. Do you know how much power and bandwidth comes with that?

So the power/connection/rackspace is all configurable. If you click on Order now you will see the options that come up.

I see 1A at 120V at $15 per month is

15/(120*24*30)*1000=$0.17 per kWh

if running flat out for the entire month.

Do you know whether 1A refers to the peak current regulated by a breaker or a fuse or whether it corresponds to the average current during the month as measured by a meter?

1Amp is referring to peak usage. However it is not hard limited to 1Amp.
Only time it gets hard limits (breaker) is when you get to 15Amps and above.

Thanks. Since a Pi consumes around 8 watts under load, then at those rates a single Pi could cost

8/120*15=$1/month

just for the electricity. That makes the rental of $5/month for the Pi look better and better.

I've written a description about mounting root on an iSCSI network block device

viewtopic.php?f=36&t=274553#p1663409

Simply install the open-iscsi package, generate an initial RAM filesystem and update cmdline.txt with appropriate options. Note once you have a suitable initial RAM filesystem that pivots root to an iSCSI disk, then full network booting should be only a small additional step.

I thought I would draw your attention to my thread in case you missed it. Are you having any luck with network booting?

Only for $5 for the 16GB and $7.50 for the 256GB.

I've been thinking how I would set this up and wondered whether you have done anything to physically disable the onboard WiFi and Bluetooth radios in the Pi computers. Doing so might be necessary, since otherwise a renter could use the WiFi to scan the access points and monitor the coming and going of nearby mobile devices. It is also possible known weaknesses in the Bluetooth pairing protocol might be put to bad use.

Can you VNC to these pi's?

Is it possible to rent multiple and run a Cluster Pi configuration like OctoPi.

Use rdp, or spice... vnc is garbage

"like octopi"
do you know what octopi is?
