How cheap serverless realli is?

The most compelling reason for having a Serverless architecture is cost. In most cases this means that you only pay for the time your app is running which sounds great. Why would you want to pay for something while it's not even running?

However, sounds like things are not that simple nowadays. With Serverless comes a lot of side costs like storage, execution time, and sometimes even bandwidth consumed. In this talk we will break these down and show you how cost effective Serverless really is based on different numbers. It's going to be mind blowing, at least my mind was blown when I found out. So are you ready to be spoilt 😁?
