For Cloud Foundry, Java is just one runtime target, provided by build packs.
You can run whatever you like, even Windows stuff. You only need to have (a) build pack(s) (aka runtime layer) and a stemcell (base operating system).
CF is like Heroku on steroids or like Lamda+API Gateway+Services for more complex applications.
And Pivotal provides one product of Cloud Foundry (
Pivotal Cloud Foundry), that can be deployed to various Cloud Providers (such as AWS, Azure or OpenStack). There are other vendors, like IBM (Bluemix).
I guess, you mixed it up with the Spring ecosystem, which surely a big driver in the adoption of Cloud Foundry. Pivotal is the core maintainer of the ecosystem.
And no, you don't need to be a big enterprise to run a CF.
