Options are :

  • None
  • To calculate the bottleneck or limiting layer was calculated. select the new metric, and set tn. metric thresholds limiting values, which are beginning to response delay. (Correct)
  • Lift the Cloud Watch Alarm threshold associated with Auto Scaling group, so scaling takes more or growth in demand prior to the start.
  • Set a longer cooldown time of the Group. so the system stops overruns the target capacity. The question is whether that scaling the system doesn YT enough time for new cases begins servicing requests before the measurement of the aggregate load again.
  • Instead, use the larger cases much smaller, so the Group will cease scaling out so much and wasting resources as the Os level, because the OS to use a greater proportion of the resources of smaller cases.
