Can you give a technical explanation of how this actually works? Heroku works by compiling your git repository with a buildpack into a "slug" and then booting that slug on a cookie-cutter LXC image running on an EC2 VM, according to process types you defined in your Procfile and the scaling you set through heroku's API, and then routing web traffic to your web processes. etc etc.
Can you explain with some technical depth how you are actually deploying/configuring the app, what languages/libraries are supported, where/how DBs & external services are run/connected to, how web traffic gets routed/proxied to the apps, etc?
