hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Understand provisioned concurrency role
Provisioned concurrency keeps function instances warm to avoid cold starts.Step 2: Understand reserved concurrency role
Reserved concurrency guarantees capacity to handle burst without throttling.Step 3: Combine both for burst handling
Setting both to burst size ensures warm instances and reserved capacity.Final Answer:
Set provisioned concurrency and reserved concurrency to the burst size. -> Option BQuick Check:
Provisioned + reserved concurrency = burst readiness [OK]
Quick Trick: Use provisioned + reserved concurrency to handle bursts smoothly [OK]
Common Mistakes:
MISTAKES- Using only reserved concurrency causes cold starts
- Using only provisioned concurrency risks throttling
- Relying on default scaling for sudden bursts
