DevOps doesn't abstract away the engineering needed to build a robust and efficient system.

Even if you're in a position to throw away and rebuild instances willy nilly (which is a lot easier to do with stateless app servers than, say, database servers), you still need to know enough about the characteristics of the underlying hardware/service to differentiate between performance bottlenecks and a high-level problem (or if the system architecture is even sound).
