You really nailed it. Among my duties are systems administration for a company that works with a lot of software development vendors. We have a user acceptance team that makes sure that we get what we ordered, that the QC stays at a high level. So functional problems, that's their deal. But they're not sysadmins, they can't easily see what developer choices make administering the servers more complicated, more fragile, more expensive, or more insecure. This shifts my job from the end of the process (here, run this!) to the beginning (hey guys, let's use these tools instead, it'll make everyone's lives easier). As such I'm very pro containers as they will eliminate a ton of deployment effort and allow me to manage different environments much more easily. But it means that there needs to be a much bigger magnifying glass on the container contents early in the process as opposed to the moment of deployment.
