The problem is still there though. For example, scaling a database to handle terabytes of data and millions of users is still really hard. Most companies have a team that can't actually do that. But they don't have to. They can use RDS or Aurora. And some really experienced engineers at Amazon will do it for them.
But these companies still experience the same grinding to a halt when they find the edges of what comes out of the box with AWS. Maybe it's just coming much later than with frontend.
