I’ve been having those discussions with friends for the last 3 or 4 years. The downside of having local infra is pretty much having someone that has the experience to do it right. While this article covered the higher end, the math on the lower end tends to work out at 1 year of ownership depending on what you already have because you will probably already have a small rack and some networking gear.

My main concern is that at the current cloud premiums rates, I will be better off even if I need to hire someone specifically for managing the local infra.
