As of today the plan is:
- create a proof-of-concept deployment in the eqiad datacenter, called eqiad2dev for testing, research and development purposes.
- expand the WMCS hardware capacity in codfw, including rack, switches and ceph.
- this will allow to create a customer-facing deployment in the codfw datacenter, called codfw2, that will be the future main Cloud VPS deployment.
