They specifically referred to bare-metal deployments (presumably local). While you could deploy SmartOS locally and run Triton yourself, I have a feeling that running a control plane like Triton is a bit overkill for a self-hosted deployment. Not to mention it likely takes several days too.

There is "CoaL", or "Cloud on a Laptop" from Joyent just to get the feet wet with Triton:

this video demonstrates that it doesn't take days and the description even says it is just as suitable for bare metal as it is for VMware:
