struct
-like objects, i.e. ones that are largely the same as a Cstruct
instance, win in the memory department.- These tests do not try to determine what is best for very large sets of values, however; I direct the reader to http://stackoverflow.com/a/2670191 for an insight into that scenario when using a dictionary.
- Dictionaries beat out objects in access times.
- According to Wikipedia, the Python dictionary is highly optimised because it is used internally to implement namespaces. [citation needed]

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.
So it might be really unintuitive at first but lambda functions have three states.
- No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
- VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
- VPC with NAT, The best of both worlds, AWS services and web.
