Is there any easy way to tell what kind of things are infeasible/inappropriate for Lambda? I went looking for limitations and found code size/fd counts/etc [1]

Is there any easy way to tell what kind of things are infeasible/inappropriate for Lambda? I went looking for limitations and found code size/fd counts/etc [1] but I want to know more general things like "can I include native code? (a DSO to be used by python code, e.g.) -- if so, what arch?", "what AWS services can I/should I access?", etc. [1] http://docs.aws.amazon.com/lambda/latest/dg/limits.html http://docs.aws.amazon.com/lambda/latest/dg/limits.html
