Autoscaler setup or not needed?

[betatim]

For mybinder.org auto-scaling the cluster up works well. More machines get spawned without any of the "admins" noticing. What still requires manual intervention is scaling the cluster back down. See this comment for the proposal on how to make it easier for the AS to scale back down (use strategy "pack").

Manual scale down isn't difficult but yet another thing to think off.

Todo: watch how switching to "pack" works out for mybinder.org. Start with a small cluster known to a few OH users to get a feeling for the usage pattern before investing a lot of time in any particular setup (AS vs fully manual vs X).
