I was confused for a long time trying to reconcile the claim of "912 computers per rack" with what I observed in the video: 18 servers per cartridge, 16 cartridges per case, so 288 servers per case. I finally realized they must have meant cores: so 4 cores x 18 servers x 16 cartridges = 912 cores per case is probably how I would have put it.
Ballparking the size of the case based on the comparison of a single server to a business card, it looks like they're using roughly a 7U case. Anybody know more about the specs of a case-load of servers? I'd love to know what the power consumption is. If you could put 6 of those cases in a cabinet, that would be some pretty incredible compute density.
I hope they consider selling the system externally. At first blush at least it seems like it would be an ideal setup for hosting colocated trading applications.
I predict failure.
The first and main reason is, that when you have multiple containers/VMs on a single server, what really happens is that "peak" or "burst" CPU matters more, in terms of what the user (whether developer doing testing, or users of a website that are browsing it) sees as performance.
Only in very memory-intensive tasks would these servers outperform (because the memory bandwidth is dedicated to just your server and is not shared). Then again, being able to bump from 2GB to 4GB (provided the application can take advantage of it) of RAM might well minimize the issue due to caching or other optimizations.
Second, 2GB RAM is (sadly) just not enough. As an example, the Zimbra mail server barely runs in 2GB; and many other Java based programs are only fast once they have chewed up a couple hundred MBs of RAM.
This looks lovely. Requested an invite. All signs are green for the race to the 1€/month server.
Wow, this is fantastic. I signed up for a trial and spun up a server. docker works well. A quick review: 1) they have the equivalent of ec2/digital ocean 2) can create volumes that can be attached to instances. 3) can create images and snapshots 4) s3 like storage. not sure about AZs and such. 5) I tried reserving an IP but they seem to be out of it.
Only downside - I would like to know the pricing before I start using this.
If anyone from Online Labs is reading this, please let us know about the pricing!
I will give the API a try tonight.
I wonder how similar this is to their existing dediboxes; I have an €5.99/mo box with them which is some kind of VIA Nano-based Dell that is only sold in Europe:

Nice little setup. It's slow, of course (certainly not fast enough to encode 720p H.264 in real time, for example), and the ARM architecture is bound to be faster.
I wonder if this isn't a little late to market. At this point, the major cloud providers offer such a large array of products and services that add value to their VM capabilities that I find it hard to imagine someone architecting a substantial system on this platform anytime soon.
That said, they will make a juicy acquisition target for someone who wants their tech. So I am not saying they wasted their time either.
Well, They are still going to have to figure out how to "Seamlessly" mirror nodes because it's going to suck when half of one of those boards dies. I do wish them the best as my inner nerd loves the idea.
Very pretty. What is the power density of these? 288 nodes/enclosure is pretty dense. Did you design your own enclosure/backplane as well? What are the interconnects?
How much does it cost?
The preview is free! You should expect good prices as we designed our own hardware for the cloud.
Yes, but how much does it cost?
The cards look really nice. Too bad they're not selling those and their shelf.
What processor did they use in order to put ECC on an ARM board?
Do they provide Load Balancers akin to what AWS does?
Some immediate thoughts:
These would be very interesting for low-latency network-heavy applications if each machine had a 1gbps latency-optimized network connection to the core switch wherever they're hosted. Virtualization might be fine from a throughput POV but I've seen hypervisors impose a fair amount of latency "jitter" on heavily loaded hosts. It's one of the reasons why bare metal servers can be better. I'm thinking core network router functions, certain kinds of games, etc.
Another area where I can see this excelling is high security applications, like having a cloud node that is in charge of signing things with very protected secret keys like some kind of certificate authority. Virtualization has a pretty good security record, but for high-paranoia applications bare metal is better. If you offered the ability to upload your own pre-encrypted image this would be very interesting. Not quite as good as homomorphic encryption, but that's not quite "there" yet -- still too slow to be usable. At the very least you'd have to crack into the hardware and dump the RAM to break into a system and steal a key.
Finally, make stability a high priority. With low power, low heat dissipation, dedicated hardware, and solid state everything you should have an easier path to cheaper "many nines" high-reliability service. That kind of thing is kind of expensive right now in the hosting world so you'd have some pricing power there.
/shameless plug:
ZeroTier One, a network virtualization engine for inter-container and inter-VM networking as well as VPN access, supports 32-bit ARM/Linux as an officially supported platform:
https://www.zerotier.com/download.html
It's also possible to use it with Docker very easily:
https://github.com/davide/docker-zerotier
I decided to create an official ARM build and support that platform since there were so many users on Raspberry Pi and similar, but as far as I know these binaries will run on this architecture. I signed up for a preview of Online.Net so I will test once I have a "box." :)
EDIT:
Tested with your free trial via the web terminal, and the ARM build from the above download link works flawlessly as long as you "modprobe tun" first:

Then I pinged my laptop on the desk next to me, which also happens to be on the "Earth" virtual LAN. Fun stuff. :)
Can this match Digital Ocean's pricing? At $5/month it's hard to beat.
I'd like to see them create some zones outside of Europe. For me its a deal killer to have US-based traffic leave the continent.
