Also, infrastructure fundementals do not change, now matter where they are running.

As long as dev's don't seem to understand real world limitations, (for instance, a network cannot be instantanious, and latency is not consistent) and thus leave tons of performance on the table, i think the "infra guys" will be just fine.

Also, don't forget there is an entire world out there of people making sure connections to the cloud are even possible across the internet.
