Then it should be called manageless?

Still confusing, since infrastructure you don't have to manage yourself is sometimes called "managed". It makes sense from the perspective of "you are paying us to manage this for you".

It's a terrible name, but it's been around for over a decade now so we're stuck with it.

I mostly choose not to use it, because I don't like using ambiguous terminology if I can be more specific instead. So I'll say things like "scale-to-zero".

these are just automanaged cloud servers, I guess?
