A couple of people asked about the references in the break. http://www.morganclaypool.com/doi/pdfplus/10.2200/S00516ED2V01Y201306CAC024 - free PDF of "The Datacenter as a Computer" 2nd edition.
http://conferences.sigcomm.org/sigcomm/2015/pdf/papers/p183.pdf - the Sigcomm 2015 paper the slides are based on (lots of other interesting stuff from many companies at http://conferences.sigcomm.org/sigcomm/2015/program.php). Best Regards, Phil Sykes
