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.
