Step-by-Step Solution
Solution:
Step 1: Understand scaling triggers
Scaling out happens when CPU usage exceeds the policy threshold.Step 2: Check threshold vs actual CPU
If threshold is higher than current CPU, scaling won't trigger despite high usage.Final Answer:
Scaling policy threshold too high prevents scaling out -> Option AQuick Check:
Threshold > CPU blocks scaling [OK]
Quick Trick: Scaling triggers only if metric exceeds threshold [OK]
Common Mistakes:
- Confusing MinSize and MaxSize settings
- Assuming cooldown zero disables scaling
- Thinking DesiredCapacity zero stops scaling out
