I'd shy away from writing "one off" deployment tools myself, unless I had a very specific reason to do it. My preference for automation of infrastructure provisioning these days is Ansible, although I'm starting to work with Terraform a bit at the $DAYJOB. At Fogbeam, all of our automated infra provisioning stuff is just a wrapper on top of Ansible. I don't find the YAML files to get terribly large or complex, and even if they did, I doubt hand-rolled code to achieve the same thing would be any less complex. For my money, if I wanted to do something that wasn't supported by Ansible (or similar tool of choice) I think my time would be better spent writing a module for the tool to add that support, than writing some one-off thing. But as always, "it depends" and YMMV of course.
