The vast majority of services are actually alright with a little downtime here and there. In exchange, maintenance is a lot simpler with less moving parts.

People underestimate how far you can go with one or two servers. In fact, what I have seen in ky career is many examples of services that should have been running on one or two servers and instead went for a hugely complex microserviced approach, all in on Cloud providers and crazy requirements of reliability for a scale that never would come.
