Hi Imesh,

Small addition from autoscaler side as per the yesterday state,

   - We can deploy/ hot deploy autoscale policy as a xml filr
   - Autoscaler receives cluster created event sent from Cloud controller
   when the subscription happens
   - It process the request using rules engine(drools) and calls the Cloud
   controller to spawn minimum number of instance in all Cloud partitions.
   - Cloud controller spawned the requested instances

I will send a detailed description to Autoscaler discussion thread.
