Lambda Cost Estimate

Memory: 512 MB  Duration: 100 ms  Invocations: 1,000,000/month

GB-seconds per invoke: 0.050000
Total GB-seconds:      50000
CPU allocation:        shared vCPU (< 1769 MB)

Monthly cost (us-east-1):
  Compute:    $0.0000
  Requests:   $0.0000
  Total:      $0.0000

Free tier: 400,000 GB-seconds + 1M requests/month
Tip: above 1769 MB you get a full vCPU — CPU-bound code may run faster and cost same or less.
