We have been experimenting with Adjutant, and it offers a menu of sizes (default small, medium and large). It's easy to add more sizes, but we would like to allow customers to request granular changes. For example, if a customer needs to add 10 cores and 5 instances to his existing quota. This would require some changes to Horizon, and an Adjutant plugin. Is anyone already doing this, or working in that direction? I apologize for the nonsense below. So far I have not been able to stop it from being attached to my external emails. I'm working on it.
