except private cloud, they provide software on top of servers from the third party hosting providers as public cloud (the link I shared before follows to public cloud servers, because it's easier to test the installation there)
private cloud or vpc from jelastic can be requested here https://jelastic.com/private-cloud-free-trial/
or you can have one free installation on your server via Virtuozzo DevOps https://virtuozzo.com/products/devops/
