 # Autoscaling
 
 The autoscaling will work in a “cluster per job” approach. This means that for job waiting in the queue, we will launch new cluster specifically for that job. Autoscaling will also take care of spinning down clusters. By default, a cluster is left Idle for 10 minutes before shutting down. Autoscaling is achieved with a cronjob to be able to quickly switch from one scheduler to the next.
