One could think of some strange technology in which there are no servers, but we all know that it’s not the case.

Do I need serverless at all?

It was so popular that the monthly cost of maintaining it grew up to $10,000. This is how much you pay when you have around 39 million requests per month (which gives around 15 requests per second).
