He might not be familiar with how you do things. This externalizes all that management overhead. One less thing that you (and your co-workers, and the next dude after you leave) can break. Also all the configuration settings are exposed via a neat UI rather than hidden in various files scattered out and about. Yes source control, Puppet, Ansible, Docker, etc makes this vastly simpler but then you need to hire and train people that are familiar with these things.
