For my organization, Lambda has been instrumental in allowing us to take some highly trafficked, small API services, and migrate them from NodeJS based servers that we manage to Lambda and Application Load Balancer that just works with no involvement. We're not relying on the API gateway (which is expensive and better suited for non-public APIs). Many of these APIs are Ajax type status updates, JWT issuers, authentication handlers and other utilities. We use the serverless framework to deploy the code, and it works very nicely for us. The hate is real in these comments, but for us we are able to move 500 million+/month API requests with minimal code changes, easy scaling up and down, and we were able to learn a little something about serverless architectures and their viability for other possible things in the future.
