Heroku is a leading Ruby on Rails hosting provider that prides itself on having a focused, easy to use and reliable service for hosting Rails. Heroku is excited to announce that as of June 1st, 2011 they are releasing their new Cedar stack into public beta. The new version of Heroku has previously been tested in alpha and private beta by hundreds of developers and Heroku customers. It is now ready for a public beta.

The new Celadon Cedar stack brings with it many new features including:

  • An entirely new HTTP stack which fully supports the 1.1 version

  • Long polling

  • Chunked responses

  • Async multi-connection web servers

  • A new process model, including support for background processes

  • Command-line access to real-time, filterable application logs

  • Full Node.js support

  • Ruby 1.9.2 support

  • Full isolation of processes for security and performance

  • And many more features

The release of the new Cedar stack into public beta also brings changes to Heroku’s billing structure. Effective June 1st instead of calculating billing units in “dynos” they will now be calculated in “dyno hours”. Heroku states that with few exceptions, cost will remain relatively unchanged or be less expensive for all users. As stated in their official press release, Heroku Co-founder Adam Wiggins had this to say about the release of Cedar into public beta:

“Over the past three years, we've worked with tens of thousands of developers who are building for the cloud. This new version of the Heroku platform is the culmination of what we've learned, and is a major step forward in realizing our vision to serve the millions more developers who will soon be moving to cloud app platforms,” and “The response from the hundreds of developers who have been using Cedar during our private beta has been incredible, and we couldn't be more excited to put it into the hands of developers worldwide.”
