Until now, Google has guarded its Data Center from public eye. Finally, we get a video tour...

The Tour focuses on how Google protects and secures its data centers, presumably to push Google forward at a time when security breaches are making the most news. Yet, it is also interesting to hear how the hardware/software is customized to Google's needs.

Google shows physical security, protection of data and its steps towards reliability in the data center.  Worth a good luck.
