Just this week a friend of mine was spinning up some AWS managed service, complaining about the complexity, and how any reconfiguration took 45 minutes to reload. It's a service you can just install with apt, the default configuration is fine. Not only is many service no longer cheaper in the cloud, the management overhead also exceed that of on-prem.
What managed service? Curious, I don’t use the full suite of aws services but wondering what would take 45mins, maybe it was a large cluster of some sort that needed rolling changes?
I'd gladly use (and maybe even pay for!) an open-source reimplementation of AWS RDS Aurora. All the bells and whistles with failover, clustering, volume-based snaps, cross-region replication, metrics etc.
As far as I know, nothing comes close to Aurora functionality. Even in vibecoding world. No, 'apt-get install postgres' is not enough.
