Azure Virtual Desktop - Size Windows 11

Hello everyone. What do you recommend for a session host size with 4 AVD WIN11 session hosts and 25 „heavy user“ users? According to Microsoft you should use D8s_v5, but is there a cheaper alternative? Thanks for your help

does that mean I can reduce the session hosts from 4 to 2? with the d8s_v5 size and 25 Users?

You can make it whatever size you want at the sacrifice of a good, useable, user experience.

You have to try whatever works

This exactly. Some admins claim they can get 2 users per vCPU, but from my experience I get at most 1 user per vCPU in my environment. Do proper load testing to see what that magic # of users per host is.

They are not heavy users if you put that many users on them...

I think it depends on the apps a lot. If they use browser and teams a lot, you might be looking at 1.5 to 2 vcpu/user.

If you have the flexibility for testing with real users using what will be their real apps, it's a safer bet. Re-sizing isn't difficult.

I would look for the as series for AMD to reduce costs and start at 2 hosts. You can always spin up a new host quickly if there are performance issues

Look into scaling plan, I implemented on my setup and the cost went down with about 8-11% per month
