An internal city-hall form API is invoked only a few dozen times per day and has no need for a persistent server. Which design most reduces idle compute cost?
Select an answer to reveal the explanation.
Short Explanation
A sleepy internal form doesn't need a server humming all night like a vacant lobby with the lights on. Lambda bills when someone actually hits the form—perfect for rare city-hall traffic.
Full Explanation
AWS Lambda is cost-efficient for low-duty, spiky, or rarely used APIs because you pay per invocation and duration rather than for idle EC2 hours. Always-on or Dedicated Host patterns keep billing during idle periods. Global Accelerator improves networking performance/availability; it does not replace application compute.
