A few shows back Andrew and I talked about Linux containers, Docker and dotCloud with Solomon Hykes -- and now Flynn is bringing PaaS to open source (powered by Docker).
Flynn is a Heroku-inspired system that simplifies deploying and maintaining applications. Instead of using complex configuration management systems, Flynn allows self-serve management of containerized deployments, making life easier for ops and developers.
Flynn provides a set of "PaaS Lego" including an API that orchestrates the management of containerized services across a cluster. These services can be anything from a Rails app to PostgreSQL to an ETL job. A variety of deployment systems and applications can be built on top of the API. For easy out-of-the-box deployment, Flynn includes Heroku-style "git push" deployment and management tools that utilize buildpacks.
Flynn will be 100% open source, BSD licensed, and developed in the open on GitHub.
