We can divide our physical setup into the following two categories:
By combining our multinode setup with a bare metal provisioning that configures the physical servers on a hardware level and a services categorization by using a group of nodes, we have an end-to-end approach that can quickly install a primary OpenStack private cloud in a wide range of hardware.
Depending on the number of physical machines that you would like to deploy, take into consideration the best practices and recommendations that were discussed in the previous chapters while building your first OpenStack production environment. In the current example, the following nodes need to be installed:
Three controller nodes
Three compute nodes
Three Ceph OSD...
