The developer experience for AWS serverless offerings, like Lambda, is awful. You can spend hours going down a rabbit hole of API gateway configuration, IAM roles, security policies, VPC endpoints, etc. that gives you very little in terms of useful error messages when it's not quite configured right. But, yeah, once you do set it up, the per-request cost is quite cheap. Still, I think if you consider the lost developer productivity dealing with slow deploys and environment/configuration issues, the costs are much, much higher.
