How often is an autoscaling policy evaluated?

How often is an autoscaling policy evaluated?

• A. Every 30 minutes
• B. Every 5 minutes
• C. Every hour
• D. Only when manually triggered

Answer: (A)

Autoscaling decisions are made by periodically checking current resource metrics and comparing them to the policy thresholds. The frequency of this evaluation determines how quickly the system can respond to changing load while avoiding unnecessary scale actions from short-lived spikes. The standard autoscaling policy evaluates every 30 minutes, providing a balance between stability and responsiveness. If it evaluated every 5 minutes, small fluctuations could cause frequent scaling (thrashing); evaluating hourly could miss rapid load changes. Manual triggering would remove automation entirely.
