I don't think GPUs will be big with "web services" datacenters anytime soon.
As the slides mentioned, the difference between this web-services stuff and HPC is that HPC has a much higher compute/data ratio. Said another way, this web-services stuff is all about moving data, collating it a bit, and less about intensive mathematical processing of it.
Most of the boxes in the diagrams are datastores. Block stores, object stores, columnar stores, caches. I hate to say it but... big data. Not (as) big compute.
