One could argue that reduced maintenance costs are a value from the cloud providers. E.g. when my AWS VM dies I can get a new one back in <10m (faster with automation). When my self-hosted server dies I need to have planned for that with a warm spare and someone needs to physically be connecting new hardware. AWS allows you to pay more but have a predictable constant cost.
