Does this actually solve a problem? You still need to implement the lambda interface. so as someone who hasn’t used them, containers just seem to replace the zip file format with no actual portability benefit
Speculative, but had we used containers from the start we would likely have built "fatter" Lambdas running full web servers with an extant web framework (someone else in this thread mentioned Flask - we don't use anything like that, we have one Lambda per... function, and our functions just consume the raw Lambda event).
