The idea is similar to maintaining on-prem vs cloud
Cloud is optimized for development velocity but its nature of high margin business eventually makes on-prem more promising
It could be too late but it might be worth looking into tax saving if you have a business. Depreciation of asset is a loss and may deduct your income. (I'm NOT a tax expert)
Cloud servers have cheaper electricity, the scale of industrial-level cooling, no issues for you (as a user) with hardware failure (ie you just use a different server; it's not your problem) and can amortize their cost by running 24x7. I've seen H100 computer hours for as little as $2.
As the author notes, there are also electrical/wiring issues that cap how much compute gear you can run in a space not designed for it. I suspect a standard 20A 110V circuit can probably handle 2x RTX 6000 Pros. 15A probably can but that requires more research. Anything more than that and you're using multiple circuits, which has issues, or you need an upgraded circuit (eg 40A 240V) with all that entails (eg heavier duty cables, custom plug, etc).

During initial setup of the server I am putting together, I found that a machine with 4x Blackwell cards derated to 300W can get by on a single 120V 20A circuit. It's tight but doable. A lot depends on the power supply. I don't think it's a great idea to run 4 high-power GPUs on a single ATX-style PSU, even a beefy 1600W job.
The other questionable part is whether all four cards can temporarily spike at full power during boot, before the wattage limit is applied by the OS. Some accounts say this is possible, and if so it could shut down the party in a hurry. But I didn't see any misbehavior when I tried it.
My earlier research suggests NVIDIA does not actually cap spikes, it caps the average over short periods of time. So setting the power limit is no guarantee.
