How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Security Tools for AWS

I often get asked which tools are good to use for securing your AWS infrastructure so I figured I'd write a short listof some useful Security Tools for the AWS Cloud Infrastructure.

This list is not intended be something completely exhaustive, more so provide a good launching pad for someone as they dig into AWS and want to make it secure from the start.

Open Source

This section focuses on tools and services provided by the community and released as open-source.

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

import os
import sys
import re
import boto3
import zipfile

def parse_s3_uri(url):
    match = re.search('^s3://([^/]+)/(.+)', url)
    if match:
        return match.group(1), match.group(2)

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
