With OpenSolaris and derivatives such as illumos, we gained the ability to build a whole IT infrastructure in a single box, using virtualized networking (crossbow) to build the underlying network and then attaching virtualized systems (zones) atop virtualized storage (zfs).
Some of this was present in Solaris 10, but it didn’t have crossbow so the networking piece was a bit tricky (although I did manage to get surprisingly far by abusing the loopback interface).
In Tribblix, I’ve long had the notion of a router or proxy zone, which acts as a bridge between the outside world and a local virtual subnet. For the next release I’ve been expanding that into something much more flexible and capable.
I’m continuously impressed by the work Peter Tribble is putting into Tribblix. Maintaining a distribution of something like OpenSolaris is hard enough as it is, but to then also add various unique functions and capabilities, while also maintaining support for SPARC, is just amazing.
