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.

Compile with:

webpack --config vendor.webpack.config.js
webpack --config app.webpack.config.js

Use with the following index.html

Zone Motivation

Make writing asynchronous code easier by having a consistent way of propagating "context" across related asynchronous operations. Have the "context" be responsible for async-local-storage, allowing the execution before and after hooks, and "context"-local error handling. Finally make sure that the "context"s are composable.

This feature needs to be part of the platform so that library and framework authors can relay on a common well know API, otherwise adoption will be limited.

Below is the list of modern JS frameworks and almost frameworks – React, Vue, Angular, Ember and others.

Redux Chaos Monkey

This is a proof of concept which allows you to replay system events in a random order each time to make sure your UI can tolerate variable states.

I'm not sure if this is worthy of its on open source project with additional features like changing play back time, whitelisting/blacklisting actions etc but figured I'd put this out there to see if it piques anyones interest.

Ansible

Understanding Ansible

Ansible is a powerful, simple, and easy to use tool for managing computers. It is most often used to update programs and configuration on dozens of servers at once, but the abstractions are the same whether you're managing one computer or a hundred. Ansible can even do "fun" things like change the desktop photo or backup personal files to the cloud. It can take a while to learn how to use Ansible because it has an extensive terminology, but once you understand the why and the how of Ansible, its power is readily apparent.

Ansible's power comes from its simplicity. Under the hood, Ansible is just a domain specific language (DSL) for a task runner for a secure shell (ssh). You write ansible yaml (.yml) files which describe the tasks which must run to turn plain old / virtualized / cloud computers into production ready server-beasts. These tasks, in turn, have easy to understand names like "copy", "file", "command", "ping", or "lineinfile". Each of these turns into shell comma
