I find it fascinating that people react so violently to the notion that virtualization is dying.  And being ex-VMware myself from the pre-IPO days, there&#x27;s no need to sell me on the virtues of virtualization.<p>The point is, when you&#x27;re talking about building up large datacenters from scratch, virtualization is an unnecessary expense.  My ex-VMware coworkers have spread through the Valley, and when I chat with them, they are saying the same things.<p>Apple Siri is 100% on bare metal and Mesos.  My friends at Uber also say the same thing, that they don&#x27;t use virtualization at all, and the ex-VP of engineering of VMware is there now.  My friends at HDP who see a lot more customers and installations that I do say that they haven&#x27;t seen any of their customers using virtualization at all, they see bare metal and mesos&#x2F;yarn.  Someone on the previous thread mentioned Spotify is the same way.<p>If you&#x27;re building up a datacenter from scratch, the trend is to now use bare metal and avoid virtualization altogether.  Sure, if you&#x27;re currently a datacenter with virtualization, you&#x27;re not going to rip it out.  As I mentioned above, it&#x27;s not dead, and it will still be around 10 years from.  But it will be relegated to a legacy app.
