I run a cloud SaaS company (3 employees). If I had the skillset that it sounds like you do, I might be inclined to hose on bare metal. But I don't. I don't know what a 1U dual socket server is.

It would take me some time to build these skills, and to match the agility that the cloud offers. I don't think it's worth my time, and probably not the author's time, either.
