Cloud Foundry is an open-source application platform that lets developers deploy cloud-native applications with a single command, without writing Kubernetes or infrastructure configuration themselves. It supports languages including Java, Node.js, Go, Python, PHP, Ruby and .NET, and is released under the Apache 2.0 licence. The project is run by the Cloud Foundry Foundation, a Linux Foundation project.
Cloud Foundry has no vendor cloud of its own. Organisations run it on their own servers or on infrastructure they choose, which makes it a self-hosted option for European organisations that want to decide where applications and data reside. The Linux Foundation, which hosts the Foundation, is a non-profit organisation under US tax status 501(c)(6). Commercial platforms built on Cloud Foundry are separate services and should be assessed on their own terms.
