    System Design Cheatsheet


Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps


Clarify and agree on the scope of the system


User cases (description of sequences of events that, taken together, lead to a system doing something useful)

Who is going to use it?
How are they going to use it?

                Steps to set up one tunnel IPSec Site to site VPN on AWS and a VM on another cloud provider (Packet) running Strongswan
              
          
    This document outlines the steps to set up a one tunnel IPSec Site to site VPN on AWS and a VM on another cloud provider (Packet) running Strongswan.
(References:
https://docs.aws.amazon.com/vpn/latest/s2svpn/SetUpVPNConnections.html
https://openvpn.net/vpn-server-resources/extending-vpn-connectivity-to-amazon-aws-vpc-using-aws-vpc-vpn-gateway-service/)
Spin up packet VM and install strongswan

(This can be any cloud provider. It does not have to be Packet)

                Download a file from a URL using Node.js
              
          
    Download File from URL

Proof-of-concept to download a file from a URL and save it locally. For example, I may wish to retrieve a JAR file from Nexus.
Uses the http package, which does the basics with raw HTTP protocol support.
Possible update: use request, it is like the Python's requests library. There is a companion package called node-request-progress that tracks download progress. See request-progress on GitHub.
Note: The request package has been deprecated.

### Device with Google Authenticator must have root.
### Computer requires Android Developer Tools and SQLite 3.

### Connect your device in USB debugging mode.
