Given that it takes significant time to image a new host, but much less time to boot a host, it would be a significant cost-saving (and energy-saving) measure to be able to specify a desired number of Running Available hosts in addition to the current option to specify the total number of desired Available hosts for a pool. This would allow us to have the necessary number of Available hosts ready to use on short notice without paying to have all of them running all of the time, as having one or two running at any time should be enough to address immediate needs; the next available machine can be booted and ready in only a minute or two after a running one becomes used.
Autoscale option for number of available (i.e. unassigned) hosts to have running

I might not be understanding your feature request correctly, but I think we already do what you want. :-)
In the Host Pool Sizing options for Auto Scaling, there is the Base Host Pool Capacity setting. This is the total number of VMs that you need regardless of their running or stopped state. Then you have the Min Active Host Capacity setting that allows you to set the minimum number of running hosts in the pool.
For periods of (perhaps) unforeseen demand, you also have the Burst Beyond Base Capacity setting that would allow VMs to be created beyond the base capacity number. This is the step that would be resource/time intensive as the VMs must be created, not just started.
I hope this helps, and if not, I look forward to your next post! Thanks so much for using Nerdio!
I think that the settings you are referring to are for a different type of pool than we have, as I don't see them. Our pools are user-assigned single-session desktops. All I have is under Auto-Grow “Add a new host when the number of available (not assigned to a user) falls below <specify number>”. So what I'm suggesting is a second option to specify the number of “available” machines to keep running, whereas right now, it keeps all available machines running for the whole working day.
