Heroku for Everything

Heroku recently GA'd the cedar stack which introduced polyglot support for various languages like Ruby, Python, node.js, or Java. Heroku for X. This month we announced "Buildpacks", which has allowed us to build support for a wide variety of programming languages. This talk will cover the what, why, and how on Buildpacks.

This talk was given at SF Rails.
