'Celadon Cedar' is the newest runtime stack for apps hosted on heroku.com. It is a polyglot platform, supporting multiple languages including Ruby, Python, Java, and Clojure.

Cedar has several improvements over Heroku's earlier stacks:

  • It uses the process model to declare, manage, and run processes across a distributed environment
  • Different types of processes can to scale at different rates to meet demand
  • Aggregate logs and process transparency give users improved process visibility into app behaviour
  • Increased user control over app releases
  • Language support is implemented through modular, customizable buildpacks, allowing developers to add support for any language or framework they need
