Enterprise Desktop Usage | Ubuntu Advantage

I would like to meet (real or jitsi) system admins that run Ubuntu desktop for other users, from 200 machines upwards.

If and why you use ua or not, and what other tools: auto install, auto updates, monitoring, user sw requests, on which architectures, os/release change management, all of this benchmarked (time to run item).

Since I prefer realtime chat, also IRC or element is fine.
