You're presumably still handling package installation, deployment etc. via something handled in-house, no? Certainly the "tending hardware" part of sysadminry is outsourceable, but unless you're going full-serverless there's still a bunch of systems work to do - so it may be longer before a full time sysadmin is worth the money, but one will likely be value for money eventually.
