You pay a premium to let your devs work on what matters, the actual product, not tinker with devops tools for hours on end on something that has already been solved. Something to keep in mind is that infrastructure code has to be updated and maintained as well, with services that gets handled for you. It would be interesting to see how much of a difference in price it would make over eg. a year.
I'm hosting at a colocation for X bucks a month. Solely the RAM I have on my servers costs X bucks a month at AWS/Azure. Maintenance overhead is small, maybe a couple hours a month.
