Undercloud and Overcloud

I was thinking to separate this into 2 days. But, to understand undercloud better, I need to know what is overcloud. :)

Undercloud is the very basic setup and infrastructure that is required to setup the "cloud infrastructure" -- overcloud, to be used by consumer. It deploys and manages overcloud.

Red Hat OpenStack Platform (RHOSP) Director is the undercloud that that deploy and manage a complete overcloud infrastructure.

The overcloud, is the production cloud that is used to deploy VMs and containers to perform cloud workload.
