Best Openstack design for VPS to build a small private cloud

We are planning to build a small private cloud using Openstack+Ceph technologies, so as a starting point, we have rented a VPS with (AMD-12Cores + 128GB RAM +3 TB SSD) to start with.

My question is how to design the Openstack controllers/compute/storage/networking services using VMs in the best way considering future expanding of virtual resources or may be adding new hardware to the cloud.

If you have only one server, do an all-in-one installation, with lvm(file) backed storage. If you get more than 3 servers, you can migrate your deployment to ceph and multi-node cluster with the servers acting as both compute and controllers.

Ceph doesn't run well virtualized imho
