• Google has always been a big linux user. When they first started they had a load of old desktops cobbled together to build the server(s) and I think they ran on that model for a long time. Using cheap commodity part which they can just add in extra nodes when needed, keeps the system flexible. What they do now I don't know. It would be nice to think they still have the original servers running away somewhere still doing there bit occasionally. I expect they have died.
