Both things have been introduced recently, and let you access even private ec2 instances

1. Without VPN
2. No open SSH port
3. Authentication / Authorization is fully delegated to IAM

# Assumes valid AWS Credentials in ENV

Using Mastodon with Backblaze B2

Mastodon can store its assets in Amazon S3 (it speaks the S3 protocol). But it does not, by default, speak to Backblaze B2.

There are a couple of reasons why you might want that:

• you already know and trust B2
• it's cheaper
• you do not want to make your instance dependent on AWS
• etc.

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?
