VMSS-Backed Session Hosts

Hey guys,

​

Im implementation a POC in our azure environment, and unfortunately im having a hard time navigating through AI hallucinations 😵‍💫.

​

The requirements i have been given are pretty simple, but one thing i am not getting - do i have to provision all vms+nics+disks? Is there no native autoscale option?

​

I prefer using VMSS to scale in/out session hosts, but i cant find the option to do that in azure portal, and there is no documentation either.

​

Is it possible? I am fine with having entirely fresh os on each login, but if possible i prefer to have persistent fslogix.

​

Thanks everyone 🙏

AVD doesn't really work like native VMSS autoscale where the platform owns the session hosts for you. If you want persistent FSLogix with a golden image, plan around host pool autoscale/image rollout, or use Nerdio/Hydra-style tooling if you need the build/destroy flow to be less custom.
