Use-Case:

Rails is built around the stateless web-page model.  This is really at odds with Vertebra's Use-Case, long-running operations.  If it takes three minutes to execute a /vm/reboot(env=/env/45) operation, it won't do to block the web-request for the whole time.  The way that web-applications handle these things is with AJAX requests that monitor whatever long-running operation is happening on the backend.

Solution:

To accommodate the needs of AJAX requests, we need an agent that acts as a surrogate for the web-application, while providing a friendly polling API.  Since Vertebra operations are run from a specific point, we also need to consider that this gateway may require some mechanism to sort out which gateway is being used (at least in the event that multiple gateways are being used in parallel for availability and load-distribution).

Design:

def do_something():
  exited_on_a = False
  exited_on_b = False
  exited_on_c = False

  while 1:
    ...
    if some_condition:
      exited_on_a = True
      break
