As a top-posting IT generalist pleb, can someone explain why Google/Yahoo did not already encrypt their data between DCs? Why is my data encrypted over the internet from my computer to theirs, but they don't encrypt the data when it goes outside their building and all the fancy access controls they like to talk about?
Its about the CPU cost of the crypto. I was once told the number of CPUs required to do SSL on web search (which I have now forgotten) and it was a bigger number than you'd expect -- certainly hundreds. So, crypto costs money at scale basically. Cheers, Michael
