In the world of clouds, horizontal scale is king. Running your OpenStack control services (APIs, message buses, databases, etc.) on a service cloud is a great way to achieve horizontal scale in a cloud friendly manner. Unfortunately, while OpenStack on OpenStack (TripleO) and OpenStack Bare Metal Provisioning (Ironic) are promising, they aren't yet ready for general consumption. While they mature it can be a daunting task to horizontally scale this infrastructure.
In this talk we will explore current, practical strategies for deploying a successful service cloud. Both the drawbacks and benefits of these immediate deployment paths will be covered, drawing on 3+ years of experience in running OpenStack clouds at enterprise scale.
