Very occasionally I need Windows for something, and then a VM would be nice, but Windows has been growing in size lately - so much that I don't want to use it anymore. So now I am trying to make do with just Linux. Otherwise, I am using VMs for edge compute, caching and cache configuration etc. I think the caches of tomorrow are those that can be fully programmed, safely in a sandbox. I used to work on unikernels, but I have become less interested simply due to the fact that while people find them interesting, in the end they all want Linux underneath.
