+Kolla's Deployment Philosophy
+=============================
+
+Overview
+========
+
+Kolla has an objective to replace the inflexible, painful, resource-intensive
+deployment process of OpenStack with a flexible, painless, inexpensive
+deployment process. Often to deploy OpenStack at the 100+ node scale small
+businesses may require means building a team of OpenStack professionals to
+maintain and manage the OpenStack deployment. Finding people experienced in
+OpenStack deployment is very difficult and expensive, resulting in a big
+barrier for OpenStack adoption. Kolla seeks to remedy this set of problems by
+simplifying the deployment process but enabling flexible deployment models.
+
+Kolla is a highly opinionated deployment tool out of the box. This permits
+Kolla to be deployable with the simple configuration of three key/value pairs.
+As an operator's experience with OpenStack grows and the desire to customize
+OpenStack services increases, Kolla offers full capability to override every
+OpenStack service configuration option in the deployment.
+
