Our AWS spend is something like $160/month. Want to come build bare metal database infrastructure for us for $3/day?
When you need to scale up and don't want that $160 to increase 10x to handle the additional load the numbers start making more sense: 3 month's worth of the projected increase upfront is around 4.3k, which is good money for a few days' work for the setup/migration and remains a good deal for you since you break even after 3 months and keep on pocketing the savings indefinitely from that point on.
Of course, my comment wasn't aimed at those who successfully keep their cloud bill in the low 3-figures, but the majority of companies with a 5-figure bill and multiple "infrastructure" people on payroll futzing around with YAML files. Even half the achieved savings should be enough incentive for those guys to learn something new.
At 160/mo you are using so little you might as well host off of a raspberry pi on your desk with a USB3 SSD attached. Maintenance and keeping a hot backup would take a few hours to set up, and you're more flexible too. And if you need to scale, rent a VPS or even dedicated machine from Hetzner.
An LLM could set this up for you, it's dead simple.
