After using lambda for a while, the opinion I've landed on is that the concept of serverless is a powerful one in specific domains, but (1) being the zeitgeist it is encouraged for use in domains where it doesn't belong, and (2) AWS Lambda itself isn't very good, for reasons that are specific to Lambda, not to the concept of serverless.
