Recommended hardware

Recommended hardware requirements for an RDO cloud:

TripleO - Production

Production deployments vary greatly but as a very brief guideline:

3 x controllers (minimum for HA control plane)
X number of compute nodes / hypervisors (can be scaled)
3 x Ceph storage nodes (optional, depending on requirements)
3 x Swift object storage nodes (optional, if not using RADOS)
