Except for the fact that a ceph cluster likes to reside in one close geographic region. You build as many OSD's as you see fit. You build at least 3 MON's. You create a CRUSH map that depicts your failure domains, so ceph can deal with data relocation and build a redundancy topology according to your physical failure domains. If you want to go for MDS, you start multiple MDS instances, with active / passive failover.
