Ok, I was working some time with Cloud Foundry as sysadmin/devops. It's big fucking enterprise piece of software which nobody know exactly how to install it and maintain. Their guide on site is obsolete, it's almost unrealistic to understand in nutshell how it works (compared with Kubernetes/Mesos-Marathon). Only info on Github pages were useful.

CF even can't even survive unplanned reboot of DC, after such incidents you literally will get parted cluster and no one know what to do.

Thank you Pivotal for such experience.
