I don't understand the appeal of serverless.

>it costs less

That's only true if you have low traffic in which case why not host from a $50/mo (at most) VPC? If a business can pay your salary then surely they can afford an extra $50/mo cloud costs.

>you don't have to manage servers

However now you have to learn to write serverless functions that will execute in an environment fundamentally different from your local machine making it more difficult to develop. So you've reduced time spent in devops and increased time spent in development.
