Google have been experimenting with POWER in their datacenters for a while now: https://www.forbes.com/sites/patrickmoorhead/2018/03/19/headed-into-its-fifth-year-openpower-has-momentum-into-the-power9-generation/ https://www.forbes.com/sites/patrickmoorhead/2018/03/19/head... More historically, Google have been building their own networking gear for some time https://www.wired.com/2015/06/google-reveals-secret-gear-connects-online-empire/ https://www.wired.com/2015/06/google-reveals-secret-gear-con... I'm focussing on Google in particular because they have always had a strong preference for Open components wherever possible and they've traditionally taken advantage that openness wherever they think they need to even if that goes against common practice. (There's a story I can't find the link to where, in the very early days, they wrote their own patches to Linux to work around some bad RAM chips that they'd scavenged from somewhere.) If Google can get an advantage then they will take it. They will also invest heavily, over years, to research these advantages and opportunities. Their attitude to things like ARM is still fairly accurate at the scale of their datacenters: https://research.google.com/pubs/archive/36448.pdf https://research.google.com/pubs/archive/36448.pdf
