The future of in-house IT Professional (SysAdmin) career in the cloud era ?

Nowadays people hear a lot about the cloud computing and its benefits, so I wonder if the IT Core Infrastructure career will still be open or useful in the near future as more and more server is now deployed in the cloud.

Please share your thoughts and comment regarding the cloud computing era and what could be the future of IT Professional when less responsibility is offloaded into the 3rd party cloud provider.
