How to setup AWS lambda function to talk to the internet and VPC

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.

Troubleshooting AWS unauthorized errors in lambda requests

This is mainly for node.js but might apply to other environments. Unsure.

If you are running a AWS Lambda function that calls another AWS service and getting an error about invalid tokens or other access denied errors, do this:

Check IAM

The role assigned to your lambda function will need permission to perform the actions. Check IAM and make sure the role has all the permissions.

Kibana 3 against ElasticSearch 1.4 throws an Connection Failed screen. The error text says to set http.cors.allow-origin, but it misses out the important http.cors.enabled: true

Working config:

$ grep cors elasticsearch-1.4.0.Beta1/config/elasticsearch.yml
http.cors.allow-origin: "/.*/"
http.cors.enabled: true
