Don't see the reason too. I mean I get it for a first project or while learning, but once you 'get' lambda using it with CDK or another framework makes you realize the whole reason for lambdas being about transformation of data not the transportation of data.

Small functions that can be reused in multiple APIs, tiny deployments, small tests incrementally building a system.

Lambdas primarily shine in an event based system. I'd rather use the serverless tooling as they're intended i.e cognito, gateway, event bridge, dynamodb.

Each are designed to solve a particular problem in what I'd say as a different paradigm.

If you want a traditional monolith I'd look to fargate instead since you'll be rolling a permission system/auth system and probably a framework of sorts.

In my past using only a part of lambda eventually lead me to having to build an already solved problem with a serverless service and make it fit in. Lessons learned I suppose.
