Your story sounds so familiar, someone could read what you wrote above and think it's me.. though I like to think of myself as a generalist rather than "fullstack". I tend to believe "fullstack" is a marketing term for acquiring slave labor. You're right though, it's required at this point for smaller startups.

> I wonder if I could ever possibly get into that fight

I wonder this too. I've been using AWS for 4+ years at my day job(s). The main pain point for almost all users, including myself is the cost. I think a product/tool that helps companies save on cloud costs would be invaluable. The difficulty is convincing crusty old ops people that the product is something worth trying.

Anyway, after my current employer runs out of money, I'm going to do a startup of some sort. While one of my many idea was like the one we outlined above, I'm actually starting to shy away from the infra/op verticals lately.

My email's in my profile, if you ever want to bounce ideas.
