Doesn’t fully convince me as having a single physical server is very different than a managed DB. If you have a disk failure you will be down until that is resolved. Which is in fact the exact scenario that happened to a client of mine and which led me to migrate to the cloud
Oh, it’s time for the cycle to flip back to on-premises servers?
With serious users, I would feel compelled to warn about the outage risks I were taking.
I actually thought the opposite. If you are small you want to move quickly and spend as much energy as possible on developing the product not managing infrastructure. There is a lot involved, OS updates, certificate management, secrets, multiple tiers of backups, but also monitoring and alerts, etc. If you have a lot of customers and server cost on the other hand, it makes sense to employ a dev ops team, that can focus on optimizing costs.
