I have a set of services that I potentially would like to migrate to AWS Lambda. My resources are behind a tradional HTTP Rest API. What I struggle to understand is that how do I structure those Business APIs. For a simple CRUD use case you have 4-5 verbs, is that then 4-5 different lambdas? for 20 resources that would be close to 100 not to mention different environments (test, staging).

Now clearly serverless people must use something else here. What am I missing? How do I go forward from here?
