Cloud Foundry is an open platform as a service, providing a choice of clouds, developer frameworks and application services. Initiated by VMware (www.vmware.com), with broad industry support, Cloud Foundry makes it faster and easier to build, test, deploy and scale applications. It is an open source project and is available through a variety of private cloud distributions and public cloud instances, including CloudFoundry.com. What is Open Platform as a Service (PaaS)? Each generation of computing ushers in a new application platform. In the cloud era, the application platform will be delivered as a service, often described as Platform as a Service (PaaS). PaaS makes it much easier to deploy, run and scale applications. Not all PaaS offerings are created equal. Some have limited language and framework support, do not deliver key application services needed for cloud applications, or restrict deployment to a single cloud. By offering an open PaaS, you get a choice of clouds for deployment, frameworks for development and application services for running your application. And as an open source project, there is a community both contributing and supporting Cloud Foundry.
