Cloud Foundry is an open source Platform as a Service that can be deployed in your own data center or hosted by VMWare. At present Cloud Foundry supports Java/ Spring applications, Rails, Sinatra, Grails and Node.js. Additional services include MongoDB, MySQL and Redis. The platform seems to be enjoying active development with the recent addition of Scala and Lift support. Cloud Foundry is an interesting addition to the growing list of PaaS solutions. It is not clear what the relationship between vFabric and Cloud Foundry will be going forward.
