I was curious about that myself. What's the best way to model the costs associated with maintenance overhead that comes with bare-metal, vs the savings from managing bare-metal servers using a service (like packet), co-locating your own hardware or running your own datacenter.
My gut feeling is that you have to get to an extraordinary size to realize any meaningful savings, but that's primarily based on Dropbox's migration off AWS (https://www.wired.com/2016/03/epic-story-dropboxs-exodus-ama...).
