I've never seen a managed IaaS that saved time. It is marketed as something that can free you from hiring ops people, but you will absolutely need to hire some supplier relations people to deal with it. (And contract optimizers, and internal PR to deal with the fallout.)

It's different for fully featured SaaS. It's a matter of the abstracted complexity vs. interface complexity ratio that is so common for everything you do in software.
