VMware Cloud Foundry
EMC VMware has positioned its open source Cloud Foundry as Linux for the cloud, providing a level of application portability across clouds. According to VMware, Cloud Foundry does not lock developers into a single framework, a single set of application services, or a single cloud. Cloud Foundry is available via public instances and private distributions. It features CloudFoundry.com, a hosted environment; CloudFoundry.org, for collaborating and contributing to the project; and Micro Cloud Foundry, a VM version of Cloud Foundry to run on a Mac or PC. CloudFoundry.com supports development in Spring Java, Ruby on Rails, Node.js, and other JVM languages. Also supported via partners on CloudFoundry.org are PHP, Python, .Net, and others.
