Remarks

In the case of the Autoscaling Application Block, if your application has a large number of roles and a large number of autoscaling rules, you may decide to run multiple instances of the Autoscaling Application Block. If this is the case, you must ensure that at any time, only one instance of the metronome is evaluating the autoscaling rules, otherwise you may submit multiple, duplicate scaling requests. This is where the execution lease come in handy.
