I think I covered those poin in calling out the cost model elements - renting the “bottom third” of the costs via managed facilities, BMaaS etc. helps in terms of reducing or eliminating capital expenses and some human toil especially in a more stable business that doesn’t benefit from per-minute lease terms or multi-year. As I called out elsewhere, sizing the hosting model to the economic model is really important.

Even in the pure rental or managed BMaaS, the human cost can quickly dominate the economic model. Owning machines and OS’s is expensive at anything more than a couple of racks of machines. Eliminating people and human change/release from touching things in the datacenter is probably the first priority. Otherwise it is hard to consistently drive that human number down and meet service quality expectations for 24x7.
