They like it enough that they bought this business from Samsung, who previously developed and supported it through their subsidiary, Joyent. I worked for Joyent for a few years but left before the transition to mnx.
That's good to hear. It sounds really cool, but also as though you need some potentially hard to come by skills to make it work (e.g. someone who used to work at Sun might find it much easier!)
I don’t think that having worked at Sun gives you much of a leg up on Triton (cloud platform). Running Triton does require specialized knowledge, but there are decent docs, IRC, and commercial support available.
Triton uses SmartOS as the operating system on compute nodes. Familiarity with Solaris/illumos is helpful at that layer. If you are
Using it to run Linux VMs, the amount of Solaris wizardry needed should be minimal.
