Now you have lots of DBs all probably operating inefficiently with only periodic recovery testing. This is the stuff DBAs do every day, and you're "hasn't happened to us... yet".
You'll be just another lesson someday
Managed databases don’t lose customer data. They would be sued and lose, and if word got out, they would lose their customers. They are optimized for the machines they run on. The proprietary tooling from AWS for managing HA clusters, doing blue-green upgrades and monitoring for slow queries is all miles ahead of the open source tooling available for self-managed databases.
There’s nothing left for the DBA to do.
So the same thing I said we do, a periodic validation of recovery, but with an acceptably short period.
SWEs can do that too. They can even write software to do most of it automatically.
They went through systems design interviews to ensure they know how to scale without picking technology choices that require a dedicated human caretaker.
It’s the opposite. Needing a DBA to operate a completely managed database is a sign of not enough maturity.
And yet here we still are
