Kinda takes this core concept and pushes it alot further and lets you boot from your own web servers - you just publish the (simple) bootrino config file plus the OS image and off you go, bootrino configures the instance and builds it from your own web infrastructure, be it internal or public.
You can see a demo of bootrino here:

The purpose of Bootrino is that it allows you to boot ANYTHING on the cloud - i.e. Unikernels and a whole zoo of other tiny operating systems, run-in-RAM operating systems, embedded operating systems etc. You are no longer restricted to running only the operating systems permitted by the cloud vendors.
Lets you do things like make RAM only Postgres databases servers, or run your web server applications purely from RAM without any login, for speed and security.
