Up until recently, BOSH has been pretty much the only tool chain for deployment of Cloud Foundry. We love BOSH for its visionary approach towards managing life cycle of clustered systems, flexibility and a distro-agnostic approach to Linux. Yet, it could be quite difficult to deploy BOSH/with BOSH. Yes, despite all its beauty, BOSH has a learning curve, and you certainly need to know its key concepts and internals to be productive. Bottom line, it takes quite a few manual steps to bring all Cloud Foundry components into a single working deployment using BOSH.
To grow the Cloud Foundry community, Altoros, Canonical, and Pivotal joined their efforts to deliver an alternative deployment tool, which would reduce complexity of Cloud Foundry deployment and decrease the number of steps. This solution is based on Juju, a service orchestration tool by Canonical.
