Hi, We are exploring various open source cloud platform. We are currently running Nutanix for our private cloud infrastructure. We would like to explore Openstack. Currently we have two clusters , one with 5 nodes and another with 3 nodes. In order to deploy two Openstack clusters what is the minimum number of nodes required for a private cloud infrastructure ensuring high availability and data integrity in mind. I will pursue the COA course however I want to have some background from industry experts since I am under the impression that Openstack deployment would require a lot of nodes for initial deployment which would be very expensive.
