I want to increase runner VM or delete runner VM.
When I increase runner VM , I wish to make instances running on different VMs.
When I delete runner VM , I wish to migrate instances from that VM to other VM.
I just want to know whether Cloud Foundry can support this? Whether there are always 4 instances?
Is it possible that CF deletes runner VM, then there are only 2 instances at that moment, and 2 instances cannot handle all the traffic?
