File under "things you will never need to do if you use cloud services".

That's not true. The RDS 5.7 instances are EOL so you have to upgrade them at some point.

At least in RDS, that will be a one-way upgrade ie: no rollback will be possible. That said, you can upgrade one instance at a time in your cluster for a no-downtime rollout.

Hosted MySQL is not what I meant. That just means you're paying more to have all the same problems. The kind of cloud service I am alluding to is cloud spanner, cloud bigtable, dynamodb.
