> Instead of paying several engineers, that you have to vet first, to configure and maintain the services adjacent to your product you can just pay AWS or Azure or someone else to maintain the service.
Your engineers who all have to possess AWS or similar certs before you hire them, work for free?
A move off VPS to managed services doesn't reduce your headcount or labour costs.
You are correct. Someone has to manage and plan the infra. But that is the same for on prem or other non cloud. What you don't necessary need is several database admins, several network admins, several kubernetes admins, etc. I don't necessarily agree, but that is the calculation. Azure hires the 24/7 admins for the service and you pay a bit more to get a share of them. I have heard this argument in person.
I think there is a very narrow space where you need the resources that this provides and it's not yet more cost effective to have your own team of admins. At a certain headcount a the number admins don't matter that much anymore.
