Serverless

• No server to manage
• Scale on real usage instantaneously
• High Availability
• Pay only for single requests

API Gateway

5 milioni * 3,50 USD/milione     = 17,50 USD

3 KB * 5 milioni = 15 milioni KB = 14,3 GB

 14,3 GB * 0,09 USD              = 1,29 USD

17,50 USD + 1,29 USD  = 18,79 USD
