I prefer something in the middle that could be called "assisted services". I want to have my hands on and know what's going on, but I am too not only a programmer and I can manage most parts of a Linux server and the infrastructure.
But, if as some oppose, you categorise an interface to configure a firewall service around your servers, then I guess I'm on to managed too, but I don't see these as managed because I still manage the rules myself.
What I like is templating to make it easier to setup non-managed services and useful feedback that keeps my maintenance time low to the necessary part. I don't want to log into 10+ servers to see if they need my attention, I want something to tell me that a server needs my attention, and that's what I would call assisted services.
If I don't know what's happening, I tend to get confused, and that's a reason I am not satisfied with managed services. Just like I would hate to own a work computer that is locked to a company policy.
