There was a time when Heroku seemed just as foreign to me as Docker does in this article.

- So shared webhosting is dead, apparently Heroku is the future?

- Why Ruby, why not just PHP?

- Wait, what's Rails? Is that different from Ruby?

- What's MVC, why do I need that for my simple website?

- Ok, so I need to install RubyGems? What's a Gemfile.lock? None of these commands work on Windows.

- I don't like this new text editor. Why can't I just use Dreamweaver?

- You keep talking about Git. Do I need that even if I'm working alone?

- I have to use command line to update my site? Why can't I just use FTP?

- So Github is separate from Git? And my code is stored on Github, not Heroku?

- Wait, I need to install both PGSql and SQLite? Why is this better than MySQL?

- Migrations? Huh?
