Very significantly different performance requirements. The client communication needs tuning for fast UI response. Unified comms (zoom, teams, etc) need to be redirected to avoid bottlenecking through the server. usage patterns aren't very well distributed (everyone logs in at 8) which means you can't over subscribe as much.

It's very different than a server workload.

Source: I run 80k of these.

In our case we have over 1500 employees using it, but only about 500 at a time. It’s an extreme waste of resources to have to provision 3x the hardware rather than use ephemeral systems. Also it’s much easier to patch a “gold” image and recompose entire pools than have to manage all of the systems as if they were full on laptops. Just to name a couple things off the top of my head.
