It was in an almost exactly similar situation to yours where I learned to do this and I've been able to scale it up to companies with 1000x more demanding infrastructure.
The funnier thing in my case was that three years after I left, the infrastructure was humming along fine with nobody actively looking at it. They never hired anyone to look after it because it never gave them any problems and they would have been fine to keep paying me to be there and do little/nothing.
I've staked my whole career on this way of doing things and I'm never looking back.
Funnily I'm in a different position at a different company and in house is a huge win for us over aws/azure due to very specific hardware requirements. There's a time and a place for everything - but the days of colocation are gone for people who don't actually need it
Understandable...and as I've mentioned elsewhere, we do also use physical hardware in datacenters. It's a situation of only for the things that need it for us.
