Right. You have to authorize to some sort of management layer somewhere. In this case at the cloud API level. It's nice that it's not directly "in band" with the rest of your application code in the same physical address space, like say SSH, but you have no idea of the actual hardware isolation involved, unless you were an engineer building said cloud.

I guess what I'm trying to say is serverless just seems like a way of shifting management layers around, giving the appearance or feeling of less management. I'm not saying thats not valuable - I haven't tried it. This is just my view from the outside.
