The financial performance looks quite alright to me, specially when looking at GCP 3rd place, and regular issues to stay relevant to big enterprises.

When not AWS, it is Azure, so the performance isn't that bad to start with.

Also AWS and GCP aren't running cloud instances of game consoles (which also use a variation of Windows), GCP one (Stadia) powered by Linux was a failure, nor are they running an AI service being used by millions of folks around the globe.

Not bad.

In my experience, Hyper-V is pretty much on par with ESX or Xen in this regard.
