I disagree here. This falls apart when you zoom out one step. I'm perfectly capable of managing a database. I'm also capable of maintaining load balancers, redis, container orchestrators, Jenkins, perforce, grafana, Loki, Oncall, individually. But each of those has the high chance of being a distraction from what our software actually does.

Its about tradeoffs, and some tradeoffs are often more applicable than others - getting a ping at 7am on a Sunday because your ec2 instance filled it's drive up with logs and your log rotation script failed because it didn't have a long enough retey is a problem I'm happy to outsource when I should be focusing on the actual app.
