Some immediate thoughts:<p>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.<p>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.<p>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.<p>/shameless plug:<p>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:<p><a href="https://www.zerotier.com/download.html" rel="nofollow">https://www.zerotier.com/download.html</a><p>It's also possible to use it with Docker very easily:<p><a href="https://github.com/davide/docker-zerotier" rel="nofollow">https://github.com/davide/docker-zerotier</a><p>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." :)<p>EDIT:<p>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:<p><a href="http://i.imgur.com/FmB9ndK.png" rel="nofollow">http://i.imgur.com/FmB9ndK.png</a><p>Then I pinged my laptop on the desk next to me, which also happens to be on the "Earth" virtual LAN. Fun stuff. :)
